There is a concurrency issue in MiniYARNCluster shutdown > logic which leads to this. Sometimes RM stops before an app master sends it's > last report, and then the app master keeps retrying for >6 minutes. In some > cases it leads to failures in subsequent tests, and it affects performance of > tests as app masters eat resources. -- This message was sent by Atlassian JIRA (v6.1#6144)
