Karthik Kambatla updated YARN-4464: ----------------------------------- Target Version/s: 3.0.0 Priority: Blocker (was: Major) Hadoop Flags: Incompatible change Agree that the value is too high in branch-2. We advise our customers to lower this all the time. However, changing it in branch-2 would be incompatible. I think we should do this only on trunk; making it a blocker so we don't miss it. How about setting the default to 0? > 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 > Priority: Blocker > > 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.
