>          Components: ambari-server
>            Reporter: Laszlo Puskas
>            Assignee: Laszlo Puskas
>             Fix For: 2.5.0
>         Attachments: AMBARI-20175.b-2.5.scripttimeout.patch, AMBARI-20175.b-2.5.v2.patch
>   Original Estimate: 24h
>  Remaining Estimate: 24h
> 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)
