Subject [jira] [Created] (YARN-4165) An outstanding container request makes all nodes to be reserved causing all jobs pending

Weiwei Yang created YARN-4165:
---------------------------------

             Summary: An outstanding container request makes all nodes to be reserved causing
all jobs pending
                 Key: YARN-4165
                 URL: https://issues.apache.org/jira/browse/YARN-4165
             Project: Hadoop YARN
          Issue Type: Improvement
          Components: resourcemanager, scheduler
    Affects Versions: 2.7.1
            Reporter: Weiwei Yang


We have a long running service in YARN, it has a outstanding container request that YARN cannot
satisfy (require more memory that nodemanager can supply). Then YARN reserves all nodes for
this application, when I submit other jobs (require relative small memory that nodemanager
can supply), all jobs are pending because YARN skips scheduling containers on the nodes that
have been reserved.
