KWON BYUNGCHANG created YARN-4464:
-------------------------------------
Summary: default value of
yarn.resourcemanager.state-store.max-completed-applications should lower.
Key: YARN-4464
URL: https://issues.apache.org/jira/browse/YARN-4464
Project: Hadoop YARN
Issue Type: Wish
Components: resourcemanager
Reporter: KWON BYUNGCHANG
my cluster has 120 nodes.
I configured RM Restart feature.
{code}
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].
