--------------------------------------
Summary: RU: Core Slaves restart schedule is extremely slow on
very large cluster
Key: AMBARI-13065
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.
