> Key: AMBARI-9197
> URL: https://issues.apache.org/jira/browse/AMBARI-9197
> Project: Ambari
> Issue Type: Bug
> Components: ambari-server, ambari-web
> Affects Versions: 1.7.0
> Environment: HDP 2.2
> Reporter: Hari Sekhon

> Ambari server has recently had added the ability to cancel operations (AMBARI-1897) but is not able to cancel operations that are timing out in yellow and gets stuck in this state for several minutes.
> I've attached a screenshot which shows there is no X next to the operations in yellow that are stalled.
> This is the result of a hang on a client but highlights that Ambari server's ability to cancel operations needs hardening. I've raised the scenario for the agent hang in AMBARI-8768.
> For expedience I had to forcibly mount hdfs nfs to recover the ambari agent and then bounced Ambari server to clear it's blocked operations queue so I could continue restarting services with updated configs.
