Ray Chiang commented on YARN-4464: ---------------------------------- Agree about making this trunk-only. One thought. If we change the default value to 0, it would be good to verify that we never actually create a local state store file or open a ZK connection. It would be wasteful to actually do any file/network open if we're going to send nothing. > 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 > Assignee: Daniel Templeton > Priority: Blocker > Attachments: YARN-4464.001.patch > > > 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.
