-----------------------------------

             Summary: Apps Pending Metrics can have incorrect value on RM recovery restart because of Unmanaged apps.
                 Key: YARN-10523
                 URL: https://issues.apache.org/jira/browse/YARN-10523
             Project: Hadoop YARN
          Issue Type: Bug
            Reporter: Minni Mittal


This Jira handles the following scenario for AppPending metric on RM restart when recovery is enabled:

AppsPending Metrics increments for each application which is final state is none on RM restart. For applications where there is a container to recover, those applications get decrement from the metric. 

For unmanaged applications when there is no container to recover, this metric doesn't get decrement, which makes the value of the metric incorrect.
