At least two UT failures (TestClientRMTokens and TestAMAuthorization) also appears in other unrelated JIRAs, such as YARN-3150 (a documentation patch). > JVM and UGI metrics disappear after RM is once transitioned to standby mode > --------------------------------------------------------------------------- > > Key: YARN-4983 > URL: https://issues.apache.org/jira/browse/YARN-4983 > Project: Hadoop YARN > Issue Type: Bug > Reporter: Li Lu > Assignee: Li Lu > Attachments: YARN-4983-trunk.000.patch, YARN-4983-trunk.001.patch, > YARN-4983-trunk.002.patch > > > When get transitioned to standby, the RM will shutdown the existing metric > system and relaunch a new one.
