[jira] [Created] (HIVE-22725) Lazy evaluate HiveMetastore::fireReadTablePreEvent table computation

 Summary: Lazy evaluate HiveMetastore::fireReadTablePreEvent table 
computation
 Key: HIVE-22725
 URL: https://issues.apache.org/jira/browse/HIVE-22725
 Project: Hive
  Issue Type: Improvement
Reporter: Rajesh Balamohan


"TransactionalValidationListener" gets added in the pre-event listeners of HMS 
by default. 

[https://github.com/apache/hive/blob/master/standalone-metastore/metastore-server/src/main/java/org/apache/hadoop/hive/metastore/HiveMetaStore.java#L559]

This causes issue in short select queries, as table details are computed for 
any partition lookups.

[https://github.com/apache/hive/blob/master/standalone-metastore/metastore-server/src/main/java/org/apache/hadoop/hive/metastore/HiveMetaStore.java#L4984]

It would be good to lazy evaluate table lookup in this codepath.

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.

Alan.

LGTM, just minor comments


service/src/java/org/apache/hive/service/server/HiveServer2.java
Lines 437 (patched)


do we have constant for "hs2" literal?



standalone-metastore/metastore-server/src/main/java/org/apache/hadoop/hive/metastore/HiveMetaStore.java
Lines 10135 (patched)


small nit: you can use static import to reduce log command length (i.e. use 
LOG instead of HMSHandler.LOG)

Reduce Sink operator orders nulls first
===
1. Set the default null sort order by hive config when creating Reduce Sink 
Desc.
2. Hash join uses 
`org.apache.hadoop.hive.serde2.binarysortable.fast.BinarySortableSerializeWrite`
 or `BinarySortableDeserializeRead` for selializing keys. For bigtable keys 
always ascending and nulls first ordering was hardcoded. This patch changes 
this behaviour to use the `Operator.getConf().TableDesc.getProperties()` (in 
this case `MapJoinOperator`) to setup ordering in `BinarySortableSerializeWrite`
3. Use null ordering set in ReduceRecordSource at Reduce phase when comparing 
keys in `CommonMergeJoinOperator` (This is the null ordering of the children 
Reduce Sink operators)

Reporter: Ádám Szita

Testing features of LLAP cache sometimes requires to validate if e.g. a 
particular table/partition is cached, or not.

This is to avoid relying on counters that are dependent on the underlying (ORC) 
file format (which may produce different number of bytes among its different 
versions).

HMS Hive database schema+upgrade scripts

[Zoltan Chovan]

Hi all,

I've recently done some work on the Hive database schema/upgrade files and
found the following:

   - there are two locations where we store the schema/upgrade files:
  - hive/metastore/scripts/upgrade (old)
  - hive/standalone-metastore/metastore-server/src/main/sql (new)
   - the old location includes the 'hive' folder and the hive database
   schema (this schema includes the sys and infromation_schema databases)
   - the new location is missing this entirely
   - looking at the packaging target directory the hive schema makes it's
   way in there as the directory
   
'hive/packaging/target/apache-hive-4.0.0-SNAPSHOT-bin/apache-hive-4.0.0-SNAPSHOT-bin/scripts/metastore/upgrade'
   includes the hive folder with the schema and upgrade scripts


With all this I'm a bit confused why the hive folder is not in the
standalone-metastore module. Could someone shed some light on this?

Thanks,
Zoltan
