Hi all,
I would like to have multiple users to access hive.
Does anyone try that before?
Is there any tutorial or link I can study from?
Best regards,
Jack
Thanks matshyeq,
you are right, I tested it on other sql engines and the result is the same.
(but I still find this confusing...)
SELECT 1 IN (1,2,3,NULL) ;
true
SELECT 1 IN (2,3) ;
false
SELECT 1 IN (2,3,NULL) ;
NULL
SELECT 1 NOT IN (1,2,3,NULL) ;
false
SELECT 1 NOT IN (2,3,NULL) ;
Hi Team,
Is there any Hive - Tez support matrix?
For example, Hive 1.2 should be on Tez which version?
Tez 0.5.3 only supports which versions of Hive?
etc…
My understanding is that it does not matter which version of Hive and which
version of Tez.

Thanks for your replies.
I see how extracting the first country would work, however I was hoping to
speed up my query by stopping the search once a country has been found.
Are you suggesting that I pass the whole IP table to a UDF and perform the
search myself? I've only programmed simple
Thanks Hitesh.
Should we put a support matrix on Documentation?Or maybe I missed it if it
is already there?

Hey all. I am using cloudera 5.4.something which uses hive 1.1 almost.
I am getting bit by this error:
https://issues.apache.org/jira/browse/HIVE-10437
So I am trying to update my test setup to 1.1 so I can include the
annotation.

Hi!
I use hbase column regex matching to create map column in hive, like:
hbase.columns.mapping = :key,s:ap_.*
then I have values in column:
{ap_col1:23,ap_col2:7}
is it possible to cut the prefix ap_ to have values like below?
{col1:23,col2:7}
Kindly regards

That would be in the hive documentation because it’s the dependent project and
determines its compatibility with downstream projects like Tez.

From a Tez perspective, there was a major compatibility change between Tez 0.4
and Tez 0.5. However, Tez-0.7.x and Tez-0.6.x are compatible with Tez-0.5.x.
I believe Hive 0.13 is compatible only with Tez 0.4.
For Hive 0.14 onwards ( including the Hive-1.x. releases ), they should work

It went from about 60 mins to 3 mins. Hive was traversing the whole table
multiple times, which is obviously inefficient!

Hi Jim,
I just created a page with the matrix of supported releases.
https://cwiki.apache.org/confluence/display/Hive/Hive-tez+compatibility
Although pom is a source of truth, we also work with versions of tez where
there have been no API changes (compared to the version in the pom).
Yes, 1.2
Never mind, I got it working with UDF. I just pass the file location to
my evaluate function. Thanks! :)
Nice. Would be very interested in looking at performance of such a UDF, if
you have numbers before/after.
I suspect it will be a magnitude or more faster than the BETWEEN/JOIN
clauses.
Thanks Vikram. That looks great.

Sorry, forgot to mention, the table is using thrift serde, but 'show create
table' shows the table is ROW FORMAT DELIMITED, which I think is a bug.
When select simple text format table, the query runs fine, but when select
thrift table, error occurs.
original create table statement:
CREATE
Obviously, the expected answer is always 2.
That's incorrect.
It's expected behaviour, SQL standard and I would expect every other DBs
behave same way.
The direct comparison to NULL returns FALSE. Always. Doesn't matter if
used as ,=, IN, NOT IN.
IS (NOT) NULL is the right way to handle such
Issue is with the thrift version you are using most probably.

I used thrift-0.9.2 to generate my thrift classes which solved this kind of
issue.

Thanks, mate. I have mysql run as my metadata store.
What is the next step? when I start hive (0.13 version), I just type in hive
in my command line.
Now, that is say I have two users: A and B. I would like A and B access hive
tables using hive-cli.
How can I do that?

Have you tried to start hive cli using these 2 users ? What issue did you
see ?
