Slim Bouguerra created HIVE-23041:

             Summary: LLAP purge command can lead to resource leak
                 Key: HIVE-23041
             Project: Hive
          Issue Type: Bug
            Reporter: Slim Bouguerra

As per the Java Spec

An unused ExecutorService should be shut down to allow reclamation of its resources.

Code like this is a serious resource leak in case  user fires multiple commands.

The other question that this raise is how those tasks responds to interrupt or cancel on the
thread level [~prasanth_j] any idea if one task hangs on IO what happens ?
