Description

As discussed in YARN-3045: While testing in TestDistributedShell found out that few of the container metrics events were failing as there will be race condition. When the AM container finishes and removes the collector for the app, still there is possibility that all the events published for the app by the current NM and other NM are still in pipeline,
