-----------------------------------------
Hi [~templedf],
Seems like latest patch uploaded by you is not for this jira,
Given that we have timelineserver to store the finished app information its not
required to store 10000 apps, IMO it would be ideal to have this in for
branch-2 also but may be with a better lower value like 500 or so( any val <
1000), so that its does completely break the compatability. Thoughts ?
> default value of yarn.resourcemanager.state-store.max-completed-applications
> should lower.

> my cluster has 120 nodes.
> I configured RM Restart feature.

> yarn.resourcemanager.recovery.enabled=true

> yarn.resourcemanager.fs.state-store.uri=/system/yarn/rmstore

> unfortunately I did not configure
> {{yarn.resourcemanager.state-store.max-completed-applications}}.
> so that property configured default value 10,000.
> I have restarted RM due to changing another configuartion.
> I expected that RM restart immediately.
> recovery process was very slow. I have waited about 20min.
> realize missing
> {{yarn.resourcemanager.state-store.max-completed-applications}}.
> its default value is very huge.
> need to change lower value or document notice on [RM Restart
> page|http://hadoop.apache.org/docs/stable/hadoop-yarn/hadoop-yarn-site/ResourceManagerRestart.html].
