[Hive-user] Which patch to apply out of multiple available ?

You typically want the last one only. Generally higher numbered patches are
revisions of previous ones and they're cumulative.

HIVE-1019 is still open and the last patch (from me) has conflict with the design pointed by Zheng's review and is incompatible with the latest trunk. Recently HIVE-1524 has been committed to trunk and may have fixed the issue in HIVE-1019 (at least for the parallel execution part).

Shrijeet, can you apply HIVE-1524 instead and see if that fixes your issue? If not please update HIVE-1019 with the detailed description of the problem (a simply test case that reproduces the issue would be greatly helpful).

Hi Ning,

Thanks for commenting. The error I was getting in task tracker logs was:

2010-09-04 19:37:31,736 WARN org.apache.hadoop.mapred.TaskTracker:

How ever I am still not sure if this is the same issue as Hive-1019.
The hive.exec.parallel is set to false in my case. I was contemplating if it
is indeed 1019, how will I go about applying a patch.
I will try to reproduce the problem, if I do - I will update Hive-1019 with
the relevant details.
