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

             Summary: DecommissioningNodesWatcher should get lists of running 
applications on node from RMNode.
                 Key: YARN-9608
                 URL: https://issues.apache.org/jira/browse/YARN-9608
             Project: Hadoop YARN
          Issue Type: Sub-task
            Reporter: Abhishek Modi
            Assignee: Abhishek Modi


At present, DecommissioningNodesWatcher tracks list of running applications and 
triggers decommission of nodes when all the applications that ran on the node 
completes. This Jira proposes to solve following problem:
 # DecommissioningNodesWatcher skips tracking application containers on a 
particular node before the node is in DECOMMISSIONING state. It only tracks 
containers once the node is in DECOMMISSIONING state. This can lead to shuffle 
data loss of apps whose containers ran on this node before it was moved to 
decommissioning state.
 # It is keeping track of running apps. We can leverage this directly from 
RMNode.
