> Key: MAPREDUCE-4122
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-4122
> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Components: mrv2
> Affects Versions: 0.23.2
> Reporter: Ramgopal N
>
> Application will retry "yarn.resourcemanager.am.max-retries" times before the
> job is failed,if the MRAppmaster process is getting killed continously.This
> killed count is considered for Pending applications with -ve value on CLuster
> metrics page.
> This will mis-interpret the exact number of jobs in the Pending state for
> the cluster.Even if the MRAppmaster kill count is monitored:should be done at
> the job level and not at the cluster level.
