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

     [ https://issues.apache.org/jira/browse/YARN-4165?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Weiwei Yang updated YARN-4165:
------------------------------
    Description: We have a long running service in YARN, it has an 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.  (was: 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.)
