Review request for hive.


Bugs: HIVE-13099
    https://issues.apache.org/jira/browse/HIVE-13099


Repository: hive-git


Description
-------

To support display of live operations in the WebUI, we record SQLOperations (in {{liveSqlOperations}}).

However, to support historic operations, we save all operations in {{historicSqlOperations}}, including non-SQLOperations which do not have display entries in liveSqlOperations.

This leads to a race condition depending on whether sessions use non-sql operations. Reproduce-able by issuing a 'set' operation.
