Subject [jira] [Commented] (HIVE-3723) Hive Driver leaks ZooKeeper connections
Date Fri, 23 Nov 2012 05:20:58 GMT


Ashutosh Chauhan commented on HIVE-3723:

Around line 910 if compile returns non-zero value, then also we releaseLocks(List<Lock>)
and then return. There also, we should call destroy() instead of releaseLocks.

> In certain error cases (i.e.: statement fails to compile, semantic errors) the hive driver
leaks zookeeper connections.
> This can be seen in the TestNegativeCliDriver test which accumulates a large number of
open file handles and fails if the max allowed number of file handles isn't at least 2048.
