URL: https://github.com/apache/hive/pull/3234#issuecomment-1106434642
The patch looks good, but one question: when we send in a statement via SQL
in the normaly way, where does the query state get initialized?

> 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.
