--------------------------------
Summary: 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
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.
