             Summary: Non-SQLOperations lead to Web UI NPE
                 Key: HIVE-13099
                 URL: https://issues.apache.org/jira/browse/HIVE-13099
             Project: Hive
          Issue Type: Bug
            Reporter: Mohit Sabharwal
            Assignee: Mohit Sabharwal


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.
