> I had a 3 node cluster. The ambari server node is also an ambari agent node. The server throws "Work already begun" error after all three agents had finished installing packages. Server always threw the error while dealing with agent heartbeat from the machine where it runs both the agent and the ambari server.
> I've got the error after patching my cluster with fixes from JIRA AMBARI-11045.
> SEVERE: Could not dispatch event: ActionFinalReportReceivedEvent{clusterId=2, hostname='bdavm076.svl.ibm.com', commandReportStatus=COMPLETED, commandReportRole=install_packages} to handler [wrapper public void org.apache.ambari.server.events.listeners.upgrade.DistributeRepositoriesActionListener.onActionFinished(org.apache.ambari.server.events.ActionFinalReportReceivedEvent)]
