> 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.
