+1.  Built it, ran rat, checked the signature and the hash.

Re: [VOTE] Should we release Hive Storage API 2.7.3-rc2?

[Alan Gates]

+1.  Checked the keys and the sha checksum.  Did a build and ran the
tests.  Ran rat.  I did get one failing test, but it doesn't look crucial:

TestBytesColumnVector.testConcatAndPadding:109 row 0 expected:<[?]> but
was:<[???]>

Re: Time to Remove Hive-on-Spark

[Alan Gates]

An important point here is I don't believe David is proposing to remove
Hive on Spark from the 2 or 3 lines, but only from trunk.  Continuing to
support it in existing 2 and 3 lines makes sense, but since no one has
maintained it on trunk for some time and it does not work with many of the
newer features it should be removed from trunk.

Re: What's master key in hive metastore?

[Alan Gates]

It is used in storing delegation tokens, which HS2 and the megastore need
to act on the user's behalf when reading files, launching jobs, etc.  See
DelegationTokenStore.

[ANNOUNCE] Apache Hive 2.3.7 Released

[Alan Gates]

The Apache Hive team is proud to announce the release of Apache Hive
version 2.3.7.


The Apache Hive (TM) data warehouse software facilitates querying and
managing large datasets residing in distributed storage. Built on top
of Apache Hadoop (TM), it provides, among others:

* Tools to enable easy data extract/transform/load (ETL)
* A mechanism to impose structure on a variety of data formats
* Access to files stored either directly in Apache HDFS (TM) or in
other data storage systems such as Apache HBase (TM) or Amazon's S3
(TM).
* Query execution via Apache Hadoop MapReduce, Apache Tez and Apache
Spark frameworks.

Re: HIVE-21508 and Hive 2.3.7 question

[Alan Gates]

I agree with Adrian that HIVE-21469 is beyond the scope of 2.3.7 for now.
If you want to backport it to the 2 branch I think it makes sense to put it
there in anticipation of a 2.4 release.

[DISCUSS] I propose a Hive 2.3.7 release

[Alan Gates]

Hope everyone is well.

There have been several requests on the Hive mailing list for a 2.3.7
release[1]  I've been working with Adrian Woodhead (aka Mass Dosage) on
testing the 2.3 branch.  We found two test failures there, which I've
posted a patch for at HIVE-23086 [2] (thanks Jésus for the review).

If everyone is agreeable I'll commit the changes to HIVE-23086 and put up a
release candidate for Hive 2.3.7.

[jira] [Created] (HIVE-23086) Two tests fail on branch-2.3

[Alan Gates (Jira)]

Alan Gates created HIVE-23086:
-

 Summary: Two tests fail on branch-2.3
 Key: HIVE-23086
 URL: https://issues.apache.org/jira/browse/HIVE-23086
 Project: Hive
  Issue Type: Bug
  Components: Test
Affects Versions: 2.3.6
Reporter: Alan Gates
Assignee: Alan Gates


TestPerfCli query88.q and TestMiniLlapLocalCliDriver union_fast_stats.q fail on 
the 2.3 branch.  

The TestMiniLlapLocalCliDriver failure is fixed in HIVE-14977 where 
union_fast_stats.q is removed from the list of tests run with 
TestMiniLlapLocalCliDriver.

The TestPerfCli failure is fixed HIVE-16602 where one line is added to 
query88.q to allow cartesian products:

{{set hive.strict.checks.cartesian.product=false;}}

I propose to backport these two changes to branch-2.3

I'm working with Adrian on getting a 2.3.7 release out.  That will pick up
everything that is already on the 2.3 branch.

I didn't use JDO when I wrote this because an object model is a really bad
abstraction for transaction and locks.  The solution for this is not to
move it into the object model but rather to move it out of constant
database operations and into something that will be faster and lighter
weight.  I believe Olli Draese has some thoughts on how to do this,
something along the lines of an in memory cache for reads and a WAL for
writing out locks and transaction open, commit, abort.

Given the huge impact this change would have on developers and the existing

+1.  I checked the signature and hash, did a build, and checked the rat
output.

Re: HMS Hive database schema+upgrade scripts

[Alan Gates]

The hive directory isn't for installing new instances of HMS, since the HMS
can't use Hive itself as its database.  It's for the information schema
support.  So when I moved the HMS schemas over into standalone-metastore I
didn't move the hive directory, as it served a different purpose.  I agree
it would be better to make that clear in the source tree.

Re: Submitting a Patch Against Branch 3

My thought would be to not worry about Yetus for branches, since it doesn't
work.  As long as it passes the regression tests for the branch it should
be fine.

Re: Query about itests profile

[Alan Gates]

Yes, Hive CI runs the itest tests.  But it does not run them with just 'mvn
install' on the command line.  There are a number of things that happen
under the hood in the CI infrastructure to control which .q files are run
for which driver.  You can get an idea by looking in
the itests/src/test/resources/testconfiguration.properties file.

Re: [VOTE] Apache Hive 2.3.6 Release Candidate 0

[Alan Gates]

Unless that fix is really important I say we don't push it into the 2.3.6
as this release is mainly for Spark and they've already tested with it.  My
take is HIVE-21980 isn't a crucial fix, so I say we leave it on the 2.3
branch and it will come out in a 2.3.7 release if someone needs it.

Heads up for two Hive releases

[Alan Gates]

All, this has been covered in other email chains here, but just to
summarize, we have proposals for two point releases:

1. Hive 3.1.2.  This will include only commits already on the 3.1 branch.
See
https://lists.apache.org/thread.html/722f6eb65e1ab8add8fcd938192098eb1426cb7b74a62c0252e06ea1@%3Cdev.hive.apache.org%3E
for details

2. Hive 2.3.6 This includes one (so far) backport that Spark needs to
update to Hive 2.  See
https://lists.apache.org/thread.html/e8f7406d046bd94b4c4a6108c7ae66d8f35014fb9132a6042c0b83f4@%3Cdev.hive.apache.org%3E
for details.

I've agreed to help with both of these.

Alan.

Re: Question about feasibility of porting HIVE-21584 and minor release 2.3.6

[Alan Gates]

I think it's fine to backport this and do a release.  Are we sure that's
enough to make it run on JDK11?  As noted in the bug there isn't an
umbrella issue to make it JDK11 compatible.  I don't know if anyone has
tested Hive 2 on JDK11 or not.

Are you available to do the backport?  If so, and we don't find any other
JDK11 related issues, I can create a 2.3.6 release once you're done.

Alan.

Re: Release timing for 3.1.2?

[Alan Gates]

I'm not aware of any discussions to push a 3.1.2 release.  I'm can work on
putting together a release of what's currently in the 3.1.2 line.  If we
hit issues with tests not passing or other such things are you available to
help?

[jira] [Created] (HIVE-21850) branch-3 metastore installation installs wrong version

 Summary: branch-3 metastore installation installs wrong version
 Key: HIVE-21850

 Project: Hive
  Issue Type: Bug
  Components: Metastore
Affects Versions: 3.2.0
Reporter: Alan Gates
Assignee: Alan Gates
 Fix For: 3.2.0


hive.version.shortname in standalone-metastore/pom.xml was not properly updated 
in branch-3.  It is still set to 3.1.0, which causes the MetastoreSchemaTool to 
install the wrong version.  Part of this Jira should include updating the 
HowToRelease doc to include updating this value.

Re: [ANNOUNCE] Apache Hive 2.3.5 Released

[Alan Gates]

It appears I made some mistake in the upload process, as I didn't see it
even in Apache's repo.  I've redone the upload and it's showing up in
Apache's repo now.  Not sure how long before it replicates to maven central.

[ANNOUNCE] Apache Hive 2.3.5 Released

[Alan Gates]

The Apache Hive team is proud to announce the release of Apache Hive
version 2.3.5.

The Apache Hive (TM) data warehouse software facilitates querying and
managing large datasets residing in distributed storage. Built on top
of Apache Hadoop (TM), it provides, among others:

* Tools to enable easy data extract/transform/load (ETL)

* Interactive query over terabytes sized datasets

* A mechanism to impose structure on a variety of data formats

* Access to files stored either directly in Apache HDFS (TM) or in other
  data storage systems such as Apache HBase (TM)

* Query execution via Apache Hadoop MapReduce, Apache Tez and Apache Spark
frameworks.

For Hive release details and downloads, please visit:
https://hive.apache.org/downloads.html

Hive 2.3.5 Release Notes are available here:
https://issues.apache.org/jira/secure/ReleaseNote.jspa?version=12345394=Text=12310843

We would like to thank the many contributors who made this release
possible.

Re: Question about 2.3.5-SNAPSHOT availability

[Alan Gates]

I've pushed a 2.3.5-SNAPSHOT to Apache's maven repository.  You should be
able to use that for testing.  I did not restart the nightly build, so if
we add more patches we'll need to re-upload a new snapshot.

Re: A proposal for read-only external table for cloud-native Hive deployment

[Alan Gates]

My suggestion does require a change to your ETL process, but it doesn't
require you to copy the data into HDFS or to create storage clusters.  Hive
managed tables can reside in S3 with no problem.

HIVE-21639 and Hive 2.3.5 release

[Alan Gates]

Yuming Wang and Hjukjin Kwon have proposed releasing a Hive 2.3.5 that
Spark can use.  They need to push a couple of back ports into branch-2.3
first.  See [1] and [2] for details.

I'm willing to work with them to get this done.

Alan.

Re: A proposal for read-only external table for cloud-native Hive deployment

[Alan Gates]

Would a workflow like the following work then:
1. Non-Hive tool produces data
2. Do a Hive load into a managed table.  This effectively takes a snapshot
of the data.
3. Now you still have the data for Non-Hive tools to operate on, and in
Hive you get all the Hive 3 goodness.

This would introduce an additional copy of the data.  It would be
interesting to look at adding a copy on write semantic to a partition to
avoid this copy, but you don't need that to get going.

I'm not opposed to what you're suggesting, I'm just wondering if there are
other ways that will save you work and that will keep Hive more simple.

Alan.

Re: A proposal for read-only external table for cloud-native Hive deployment

[Alan Gates]

Have you looked at the insert only ACID tables in Hive 3 (
https://issues.apache.org/jira/browse/HIVE-14535 )?  These were designed
specifically with the cloud in mind, since the way Hive traditionally adds
new data doesn't work well in the cloud.  And they do not require ORC, they

Re: Running Hive Without Hadoop?

[Alan Gates]

It depends on what you mean by run without Hadoop.  You can run HS2 without
a Hadoop cluster.  Take a look at
https://github.com/alanfgates/sqltest/blob/master/dbs/hive/v3_1/Dockerfile
for an example Dockerfile.  But Hadoop code is still needed in the path.
Hive depends on Hadoop code for a number of things and cannot build without
the Hadoop jars.

Re: [DISCUSS] Move gitbox notification emails to another list?

+1 to sending the github mail to a separate list.

I agree with Peter that seeing PR reviews is good.  Wouldn't it be possible
to craft a filter that only allowed through these mails?

Re: [NOTICE] Mandatory relocation of Apache git repositories on git-wip-us.apache.org

IIUC it's the only step necessary to have one place where we could review
and merge pull requests.  There'd be no more need for attaching patches to
JIRA.  Of course we'd need to update our CI processes to match.

Fwd: [NOTICE] Mandatory relocation of Apache git repositories on git-wip-us.apache.org

[Alan Gates]

This includes the hive project, as we're on the older git-wip-us.  Do we
want to move sooner or later?

Alan.

Date: Fri, Dec 7, 2018 at 8:52 AM
Subject: [NOTICE] Mandatory relocation of Apache git repositories on
git-wip-us.apache.org
To: us...@infra.apache.org 


[IF YOUR PROJECT DOES NOT HAVE GIT REPOSITORIES ON GIT-WIP-US PLEASE
  DISREGARD THIS EMAIL; IT WAS MASS-MAILED TO ALL APACHE PROJECTS]

Hello Apache projects,

I am writing to you because you may have git repositories on the
git-wip-us server, which is slated to be decommissioned in the coming
months. All repositories will be moved to the new gitbox service which
includes direct write access on github as well as the standard ASF
commit access via gitbox.apache.org.

## Why this move? ##
The move comes as a result of retiring the git-wip service, as the
hardware it runs on is longing for retirement. In lieu of this, we
have decided to consolidate the two services (git-wip and gitbox), to
ease the management of our repository systems and future-proof the
underlying hardware. The move is fully automated, and ideally, nothing
will change in your workflow other than added features and access to
GitHub.

## Timeframe for relocation ##
Initially, we are asking that projects voluntarily request to move
their repositories to gitbox, hence this email. The voluntary
timeframe is between now and January 9th 2019, during which projects
are free to either move over to gitbox or stay put on git-wip. After
this phase, we will be requiring the remaining projects to move within
one month, after which we will move the remaining projects over.

To have your project moved in this initial phase, you will need:

- Consensus in the project (documented via the mailing list)
- File a JIRA ticket with INFRA to voluntarily move your project repos
   over to gitbox (as stated, this is highly automated and will take
   between a minute and an hour, depending on the size and number of
   your repositories)

To sum up the preliminary timeline;

- December 9th 2018 -> January 9th 2019: Voluntary (coordinated)
   relocation
- January 9th -> February 6th: Mandated (coordinated) relocation
- February 7th: All remaining repositories are mass migrated.

This timeline may change to accommodate various scenarios.

## Using GitHub with ASF repositories ##
When your project has moved, you are free to use either the ASF
repository system (gitbox.apache.org) OR GitHub for your development
and code pushes. To be able to use GitHub, please follow the primer
at: https://reference.apache.org/committer/github


We appreciate your understanding of this issue, and hope that your
project can coordinate voluntarily moving your repositories in a
timely manner.

All settings, such as commit mail targets, issue linking, PR
notification schemes etc will automatically be migrated to gitbox as
well.

With regards, Daniel on behalf of ASF Infra.

PS:For inquiries, please reply to us...@infra.apache.org, not your
project's dev list :-).

Re: Why are TXN IDs not partitioned per database?

[Alan Gates]

History.  Originally there were only transaction ids, which were global.
Write ids for tables came later as a way to limit the amount of information
each transaction needed to track and to make it easier to replicate table
changes between Hive instances.

But even if we had put them in from the start, we'd have them span
databases, otherwise transactions couldn't span databases.  Hive has no
restrictions on queries spanning databases so we wouldn't want to restrict
transactions from doing so.

[jira] [Created] (HIVE-20451) Metastore client and server tarball issues

 Summary: Metastore client and server tarball issues
 Key: HIVE-20451
 URL: https://issues.apache.org/jira/browse/HIVE-20451
 Project: Hive
  Issue Type: Bug
  Components: Standalone Metastore
Affects Versions: 4.0.0
Reporter: Alan Gates


With the split of the metastore into common and server there are now two sets 
of tarballs.  There are a couple of issues here.
 # It doesn't make sense to have separate source tarballs for each.  The source 
release should still be done from the standalone-metastore directory and 
include all code for the metastore.
 # The binary tarballs should have separate names.  At the moment both are 
named apache-hive-metastore.

You define these two values both here and in HiveMetaStoreClientPreCatalog. 
 Wouldn't it make more sense to define them once in a shared location (like 
IMetaStoreClient maybe)?

Note that once you have created the JIRA ticket you can also reference that

Class naming isn't very consistent across much of Hive.  I'd name it

These two classes are 95% the same.  Now that HIVE-19711 has split 
HiveSchemaTool into multiple components it will be much easier to refactor 
these so that there is only one version of the code that each shares.

I removed Hive 2.1.1, 2.2.0, and storage-api-2.5.0.  I left 1.2.2 since
some people are still using Hive version 1.  I did remove the stable link
to 1.2.2 as we don't want users to think 1.2.2 is our last stable version.
There is a stable-2 link pointing to 2.3.3, which I left.  I assume once we
have a stable version of 3 (3.1?) we'll create a stable-3 link that points
to it.

Many JDBC methods include a catalog specifier in the call.  We need to update 
these to work with multiple catalogs.

Also we will need to also support the JDBC calls for catalogs.  This at least 
includes Connection: getCatalog() and setCatalog() 
DatabaseMetaData: getCatalogs(), getCatalogSeparator(), and getCatalogTerm() 
and maybe others.

[jira] [Created] (HIVE-19871) add_partitions does not properly handle client being configured with a non-Hive catalog.

If a client calls 
 {{add_partitions(List parts, boolean ifNotExists, boolean 
needResults)}}
and the catalog name is set to a non-default value in the config file but unset 
in the partitions, the request to add the partition will fail with an error 
message "table not found" even when the table is valid.

Re: Getting started with Hive

[Alan Gates]

Take a look at DDLTask.describeTable.  That is the task run by the executor
to do a describe table.  The 'Hive db' argument is a handle to the
metastore client.  'DescTableDesc descTbl' contains the information from
the parser on what table to describe.

Are you doing this just to learn the system or do you want to add more
metadata that will be returned in show and describe calls?  If this is
something you plan to contribute you should file a JIRA and discuss your
potential changes there, so that you can get feedback on the design, since
adding additional metadata tables to the system is a change others will
want to review.

Re: Getting started with Hive

[Alan Gates]

First, my apologies, I thought your first question was sent to dev@hive,
which is the right list.  Hence I've removed dev@community from my reply.
If you haven't already you should subscribe to dev@hive.

I'm not 100% sure I understand your question, but here's a place to start.
If you do "create table foo..." in SQL that will eventually end up in
HiveMetaStore.create_table.  This handles checking the table and creating
any necessary directories, and then calls RawStore.createTable, which will
end up in ObjectStore.createTable.  This is where the values you sent in
createTable get written down to the RDBMS backing the metadata.  I'm not
sure that's the answer to the question you were asking or not.

Alan.

[DISCUSS] Catalog feature in 3.x

[Alan Gates]

The base of the catalog feature made it into Hive 3, though it's not very
usable yet since it is only in the metastore.  I plan to keep working on
this feature to add it to the rest of Hive.  The (ever growing) set of
tasks for doing this is tracked in HIVE-18685.

I believe this should get pushed into branch-3 since the beginning of the
feature is in 3 and it will likely be a year or more before there's a Hive
4.

Since branch-3 currently has a number of test failures I won't start
pushing patches yet, but once it stabilizes I'd like to push this feature
into branch-3.  Any concerns?

Alan.

Cleaning up old version in dist

[Alan Gates]

Apache asks that we keep at most 2 current versions in dist, to minimize
the space we take up on distribution mirrors.  Since we are running
multiple lines and a have a couple of separately releasable modules we'll
have more than 2 versions there.  But we have old versions of Hive 2 (2.1,
2.2) and of the storage-api (2.4, 2.5).  I think we should remove these.
That will leave us with the most up to date versions of Hive 1, 2, 3, the
storage api, and the standalone metastore.  Note that this does not affect
their availability in maven central or the apache archive.

Alan.

Re: [DISCUSS] Release of standalone-metastore

[Alan Gates]

I have pushed the standalone metastore src and bin tarballs and their
signatures and hashes into Hive's dist area, so they should soon be
available for download.  Congrats to all who worked on this!

As part of creating a release tag for the standalone metastore I noticed we
didn't have one for release 3.0.0, so I created a tag for that as well.

Alan.

Re: [DISCUSS] Release of standalone-metastore

I have put the binary and source objects up at
https://home.apache.org/~gates/hive-standalone-metastore-3.0.0/ so everyone
can take a look before I officially push them to dist.

I don't think we need to vote on this as we have already officially
released these objects, I'm just adding sha and gpg signatures for download
purposes.  But, please take a look and make sure I did everything
properly.  I'll push them to dist after a couple of days to give everyone a

[jira] [Created] (HIVE-19791) Modify TableDesc to contain the catalog

-

 Summary: Modify TableDesc to contain the catalog
 Key: HIVE-19791
 URL: https://issues.apache.org/jira/browse/HIVE-19791
 Project: Hive
  Issue Type: Sub-task
  Components: Query Planning
Affects Versions: 3.0.0
Reporter: Alan Gates
Assignee: Alan Gates


TableDesc currently only contains a table's database and tablename.  It needs 
to also have the catalog name.

[jira] [Created] (HIVE-19769) Create dedicated objects for DB and Table names

[Alan Gates (JIRA)]

Alan Gates created HIVE-19769:
-

 Summary: Create dedicated objects for DB and Table names
 Key: HIVE-19769
 URL: https://issues.apache.org/jira/browse/HIVE-19769
 Project: Hive
  Issue Type: Sub-task
  Components: storage-api
Affects Versions: 3.0.0
Reporter: Alan Gates
Assignee: Alan Gates


Currently table names are always strings.  Sometimes that string is just 
tablename, sometimes it is dbname.tablename.  Sometimes the code expects one or 
the other, sometimes it handles either.  This is burdensome for developers and 
error prone.  With the addition of catalog to the hierarchy, this becomes even 
worse.

I propose to add two objects, DatabaseName and TableName.  These will track 
full names of each object.  They will handle inserting default catalog and 
database names when those are not provided.  They will handle the conversions 
to and from strings.

These will need to be added to storage-api because ValidTxnList will use it.

​Actually, there is.  The tarballs for source and bin are already out
there.  If I post them on the distribution site then they'll be easier to
find.  So we can test that now.  And we can then do a 3.1 release of the
metastore whenever we want, as long as it's before a 3.1 release of Hive.

[DISCUSS] Release of standalone-metastore

[Alan Gates]

In the thread on releasing Hive 3.0 I wrote

We should work on producing a standalone-metastore
release in the same time frame so that the schema's, etc. match. I can RM
that unless someone else wants to.

https://lists.apache.org/thread.html/307b281c3742fdf6aeb7fac3ee74a98830400b67711755572de15b80@%3Cdev.hive.apache.org%3E

My thinking was to produce a separate metastore release, like we do for
storage-api.  However, I missed that I needed to do some work in branch-3.0
to disconnect standalone-metastore from the pom before the release (in the
same way that storage-api does).  Thus when we released Hive 3.0 we also
released the standalone-metastore. See
https://search.maven.org/#search%7Cga%7C2%7Cg%3A%22org.apache.hive%22   So
I can't release another version of standalone-metastore 3.0.  Here is what
I propose we do:


   1. Put the src and bin tarballs for standalone-metastore in Hive's
   distribution site.  We have already voted on these as part of 3.0 release
   process.
   2. Like storage-api, we keep the standalone-metastore linked in the pom
   in the master branch.  This makes life easier for developers as they
   produce new patches.
   3. Also like storage-api, at some future point before we release Hive
   3.1 I will:
  1. Make a separate branch for standalone-metastore from branch-3
  2. Release a standalone-metastore 3.1 from this new branch
  3. Remove standalone-metastore from the list of sub-modules in Hive's
  pom.xml
  4. Make Hive depend on the released 3.1 version of the
  standalone-metastore.
   4. For branch-3.0, I do not propose to do the same separation as in
   branch-3, but we can make a different choice in the future if there is a
   reason to do so.

Make sense?  Thoughts?

Alan.

DB install and upgrade scripts in the brave new world of multiple release lines

[Alan Gates]

The change to have branches running with master as 4 and branch-3 for 3.x
releases is complicating our DB install and upgrade scripts.  There's a
JIRA to track the changes but some discussion on that JIRA of how best to
proceed, starting with the comment
https://issues.apache.org/jira/browse/HIVE-19323?focusedCommentId=16489833=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-16489833
I'm posting this here as others may be interested in chiming in.

Question on branches

[Alan Gates]

I have a series of patches that fix bugs in the recently released 3.0, e.g.
HIVE-19531.  I would like these to go out in Hive 3.0.1, assuming we create
such a release at some point.  Which branch(es) should I put the patch on
in addition to master?  Or to put the question another way, what branch(es)
will Hive 3.0.1 and Hive 3.1.0 be cut from?

Alan.

Re: build broken by glassfish dependency again

+1.  It can't be too important because I was able to get my build going
without the poms by copying the directory structure and pom.lastUpdated
files in from another repo.

[jira] [Created] (HIVE-19576) IHMSHandler.getTable not always fetching the right catalog

 Summary: IHMSHandler.getTable not always fetching the right catalog

{{IHMSHandler.get_table_core(String dbName, String tableName)}} fetches the 
catalog name from the conf.  This causes issues when doing an operation where 
the catalog is known and does not match the default provided in the 
configuration file (e.g. adding a partition).  This method should be removed 
and callers forced to use {{IHMSHandler.get_table_core(String catName, String 
dbName, String tableName)}} instead since callers will know whether they have 
the catalog name or not.

HiveAuthorizationProviderBase.getDatabase uses just the database name to fetch 
the database, relying on getDefaultCatalog() to fetch the catalog name from the 
conf file.  This does not work when the client has passed in an object for a 
different catalog.

TransactionalValidationListener.validateTableStructure get the catalog from the 
conf file rather than taking it from the passed in table structure.  This 
causes createTable operations to fail.
