> Key: AMBARI-11285
> URL: https://issues.apache.org/jira/browse/AMBARI-11285
> Project: Ambari
> Issue Type: Bug
> Components: ambari-server
> Affects Versions: 2.1.0
> Reporter: Di Li

> Priority: Critical
> Fix For: 2.1.0

>
> 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
