Subject [jira] [Commented] (HIVE-11515) Still some possible race condition in DynamicPartitionPruner
Date Fri, 21 Aug 2015 12:37:45 GMT


Navis commented on HIVE-11515:

[~sseth] Sorry for delay. 
I've seen this a month ago in PoC scenario sometimes and desperately made this patch in a
hurry. After applying it, those things gone and I just forget it (there was so many issues).
So I cannot remember what was the exact problem, but it seemed "query hang" situation I guess.
Sorry for my vague description.

but it seemed related to the fact that prune() is called by thread-pool. With some delay in
queue, events from fast tasks are arrived before prune() is called.
