> 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.
