Description

RMNodes in SLS don't keep a track of runningApps on each node. Due to this, graceful decommissioning logic takes a hit as the nodes will decommission if there are no running containers on the node but some shuffle data was present on the node.

In this Jira, we will add runningApps functionality in SLS for improving decommissioning logic of each node. This will help with autoscaling simulations on SLS.
