> 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.
> {code}
> java.lang.NullPointerException
>         at org.apache.hive.generated.hiveserver2.hiveserver2_jsp._jspService(hiveserver2_jsp.java:131)
>         at org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:98)
> {code}
> We should save only SQLOperations in historicSqlOperations.
