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

             Summary: ReservedContainer Node is added to blackList of application due to node
due to node can not allocate
                 Key: YARN-10395
                 URL: https://issues.apache.org/jira/browse/YARN-10395
             Project: Hadoop YARN
          Issue Type: Bug
          Components: capacityscheduler
    Affects Versions: 2.9.2
            Reporter: chan


Now,if a app reserved a node,but the node is added to app`s blacklist.

when this node send  heartbeat to resourcemanager,the reserved container allocate fails,it
will make this node can not allocate other container even thought this node have enough memory

or vcores.so i think we can release this reserved container when the reserved node is in the
black list of this app.
