Impala fails to recover from statestore connection loss while waiting for metadata

    XMLWordPrintableJSON

Details

    Description

      The following sequence:

      describe t1;
      shut down statestore
      invalidate metadata t1;
      ***describe t1;
      start ST
      

      makes the marked query hang indefinitely. New queries will work, but this query will be stuck in the planning phase. Trying to cancel the query or open the details will bring down the web UI since it will wait for the lock the query is holding. The only way to kill off these queries is a restart.
