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

             Summary: Rebalance hdfs command doesn't wait for the operation to finish 
                 Key: AMBARI-20175
                 URL: https://issues.apache.org/jira/browse/AMBARI-20175
             Project: Ambari
          Issue Type: Bug
          Components: ambari-server
            Reporter: Laszlo Puskas
            Assignee: Laszlo Puskas


The rebalancing operation may take a long time (hours, days) thus when issued from the ambari
UI the background operation may time out.

As it's not possible to dynamically predict how long the rebalancing will last , the approach
taken by this solution is to only trigger the operation and not wait to the operation to finish.


(Worths mentioning here, that after this change the progress of the rebalance operation won't
be tracked anymore in the background operation; also the user won't be notified about the
success/failure of the operation)
