Steve Loughran commented on YARN-10663:
---------------------------------------

FYI. there's refs to com.google in the code which MUST be org.apache.thirdparty.com.google; you do a build right now and maven ends up patching TestNMSimulator

> 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.
