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.
