Haibo Chen commented on YARN-7602: ---------------------------------- The unit test failures seem unrelated to me. Will update the patch to address the checkstyle issue and see what Jenkins says. > NM should reference the singleton JvmMetrics instance > ----------------------------------------------------- > > Key: YARN-7602 > URL: https://issues.apache.org/jira/browse/YARN-7602 > Project: Hadoop YARN > Issue Type: Bug > Components: nodemanager > Affects Versions: 3.0.0-beta1 > Reporter: Haibo Chen > Assignee: Haibo Chen > Attachments: YARN-7602.00.patch, YARN-7602.01.patch, > YARN-7602.02.patch, YARN-7602.03.patch > > > NM does not reference the singleton JvmMetrics instance in its > NodeManagerMetrics. This will easily cause NM to crash if any of the node > manager components tries to register JvmMetrics. An example of this is > TimelineCollectorManager that hosts a HBaseClient that registers JvmMetrics > again.
