      Description

      Running into this quite often.

      • Start Drill bit
      • Connect to Drill bit via SQL line and perform few queries
      • Stay idle for some time with no activity, SQLLine disconnects to Drill bit
      • Connect again, gives 'No DrillbitEndpoint can be found'
      • Do JPS, drill bit is still running

      The workaround is to restart Drill service (which is running) and connect from SQLine.

        Not a problem any more. I left sqlline idle for around 2 hours and it did not disconnect.

        This is pretty old, and a lot of things have changed in this area; please verify that this is still happening.

        can you confirm that the java client reconnects to zk and finds a drillbit if it loses zk connection.
