Sunil G reopened YARN-7163: --------------------------- > RMContext need not to be injected to webapp and other Always Running services. > ------------------------------------------------------------------------------ > > Key: YARN-7163 > URL: https://issues.apache.org/jira/browse/YARN-7163 > Project: Hadoop YARN > Issue Type: Bug > Components: resourcemanager > Reporter: Rohith Sharma K S > Assignee: Rohith Sharma K S > Priority: Blocker > Fix For: 2.9.0, 3.0.0-beta1, 3.1.0 > > Attachments: suspect-1.png, suspect-2.png, YARN-7163.01.patch, > YARN-7163.02.patch, YARN-7163.03.patch, YARN-7163.03.patch, > YARN-7163-branch-2.01.patch, YARN-7163-branch-2.addednum.patch > > > It is observed that RM crashes with heap space OOM in secure cluster(http > authentication is kerborse) when RM HA is enabled. > Scenario is > 1. Start RM in HA secure mode. Lets say RM1 is active mode. > 2. Run many applications so that it uses greater than 50% of heap space > configured. Lets say, if heap space is 2GB, then run applications that occupy > 1.5GB of heap space. > 3. Switch RM to StandBy and bring back to Active! While recovering > applications from state store, RM crashes with OOM. > *Note* : This issue will happen only when RM is started as ACTIVE directly. > (not switched from standby to active during start of JVM) > Heap dump shows that RMAuthenticationFilter holds 60% heap space! And other > 40% held by RMAppState which is during recovering from state store. This > exceeds the heap space and crashes with OOM. -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
