------------------------------------
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.
