--------------------------------------
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)
