Siddharth Seth updated HIVE-10106:
----------------------------------
Attachment: HIVE-10106.1.patch
I believe this is caused by the way mapWork is setup. It's now created in the
constructor of HiveSplitGenerator. The constructor and the initialize method
may not be invoked in the same thread. As a result, the initialize method ends
up seing a different copy of mapWork from the one modified in the pruner.
Attaching a patch to fix this - by setting the mapWork in the initialize method.
[~hagleitn] - please review, and validate the theory.
[~mmokhtar] - I wasn't able to reproduce this. Seing pruning work as it should
for the simple query that you'd sent me offline. May need help reproducing the
issue and validating the patch. Thanks
