[jira] [Created] (IMPALA-11090) Need a method to specify the current number of executors for an executor group

-----------------------------------

             Summary: Need a method to specify the current number of executors for an executor group
                 Key: IMPALA-11090
                 URL: https://issues.apache.org/jira/browse/IMPALA-11090
             Project: IMPALA
          Issue Type: Improvement
            Reporter: Qifan Chen


Currently, impalad accepts -num_expected_executors for the expected number of executors of a group.  The feature is very useful in testing auto-scaling feature (IMPALA-10992). 

It will be very nice to specify the current number of executors as a new parameter to impalad.

Both the current number of executors and the expected number of executors are important parameters for an executor group.
