> yarn.resourcemanager.recovery.enabled=true
> yarn.resourcemanager.store.class=org.apache.hadoop.yarn.server.resourcemanager.recovery.FileSystemRMStateStore
> yarn.resourcemanager.fs.state-store.uri=/system/yarn/rmstore
> {code}
> 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].
