Yes, that¹s the intended behaviour. I can help you get a fix in, if you
have some time to test out my WIP patches.

Thanks for the quick answer Gopal, and also for the details on that param.
I indeed use JDBC in production, so will stay away from it.

Hi,
I've been experimenting with 'select *' and 'select * limit X' in beeline
and watching the hive-server2 log to understand when a M/R job is triggered
and when not. It seems like whenever I set a limit, the job is avoided,
but with no limit, it is run.
I found this param:
hive.limit.optimize.f
Sample stacktrace is :
[Error: Failure while running task:java.lang.RuntimeException:
org.apache.hadoop.hive.ql.metadata.HiveException: java.io.IOException:
java.io.IOException: wrong key class: org.apache.hadoop.io.BytesWritable is

I have seen this issue when mixing Sequence files written by PIG with

A full stack trace would help determine is this is a Tez issue or hive issue.

Hi Team,
Env: Hive 1.0 on Tez 0.5.3
Query is a simple group-by on top of sequence table.
It fails with below error on tez mode:

Hello!
I've posted a bug on this issue:

What do you think? I can prepare a patch.
Kindly regards

We would like to assign a YARN queue to a user upon login.
Is there any way to do this outside of the box? If not, is anyone aware of
any development effort to do this?
It sounds like it would be pretty simple to extend the Connection class to
lookup a queue in a custom table in the metastore fo
10 matches
