> 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

> 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. See HBASE-19409 for details.
