Siddharth Seth commented on HIVE-14003:
---------------------------------------
[~sershe], [~prasanth_j] - is the patch good to go in (with the comments
changed to point to new jiras which will be created). I think there are
additional cases which need to be addressed; they can be addressed in a
different jira. This one, in it's current form, does get rid of queries getting
stuck on hash table creation.
> queries running against llap hang at times - preemption issues
