> Key: AMBARI-1371
> URL: https://issues.apache.org/jira/browse/AMBARI-1371
> Project: Ambari
> Issue Type: Improvement
> Components: controller
> Reporter: Olivier Renault
>
> Ability to put a node / cluster / service in maintenance mode.
> It should turn off the alerts for the component which has been put in
> maintenance mode whilst still capturing all the events / changes.
> The maintenance mode should have the option to be time controlled. For a
> datanode, I should also have the option to disable replication for under
> replicated block for a time period. eg, if i reboot, I do not want my
> namenode to start re-replicating whilst having the time control, will prevent
> human error. We could consider overwrite the data replication after 1H.
