> URL: https://issues.apache.org/jira/browse/AMBARI-13065
> Project: Ambari
> Issue Type: Bug
> Components: ambari-server
> Affects Versions: 2.1.2
> Reporter: Jayush Luniya
> Assignee: Jayush Luniya
> Priority: Blocker
> Fix For: 2.1.2
>
>
> Performed RU on 1200 node cluster and the progress of 'Core Slaves' restarts
> is extremely slow - In 3 hours it restarted only 22 components (screenshot
> attached). At this rate it will take weeks for RU to complete.
> It we look into the agent log where RU core-slaves finished, we see that
> sequential commands are sent 8 minutes apart - which is very slow. The
> commands themselves execute in under a minute.
