[jira] [Created] (HIVE-26167) QueryStateMap is SessionState is maintained correctly

László Pintér created HIVE-26167:
------------------------------------

             Summary: QueryStateMap is SessionState is maintained correctly
                 Key: HIVE-26167
                 URL: https://issues.apache.org/jira/browse/HIVE-26167
             Project: Hive
          Issue Type: Improvement
            Reporter: László Pintér
            Assignee: László Pintér


When the Driver is the QueryStateMap is also initialized with the query ID and the current queryState object. This record is kept in the map until the execution of the query is completed. 

There are many unit tests that initialise the driver object once during the setup phase, and use the same object to execute all the different queries. As a consequence, after the first execution, the QueryStateMap will be cleaned and all subsequent queries will run into null pointer exception while trying to fetch the current querystate from the SessionState.
