Review request for hive.
Bugs: HIVE-5296
https://issues.apache.org/jira/browse/HIVE-5296
Repository: hive-git
Description
-------
Hiveserver2 will occur memory leak caused by increasing Hashtable$Entry at
least 2 situation as follows.
1. When Exceptions are thrown during executing commmand or query, operation
handle will not release.
2. Hiveserver2 calls FileSystem#get method and never call FileSystem#close or
FileSystem.closeAll so FileSystem$Cache will continue to increase.
I've modified HiveSessionImpl and HiveStatement not to lose operation handle.
Operation handle is needed by OperationManager to remove from handleToOpration.
Also, I've modified HiveSessionImpl to close FileSystem object at the end of
session.
