Szilard Nemeth commented on YARN-10663:
---------------------------------------
Hi [~ananyo_rao],
Change looks good to me.
One small ask: Could you please add tests to the AMSimulator?
I can't see the mentioned logic tested anywhere:
{quote}
When the app is finishing, for each node in ranNodes list in AMSimulator, we
will remove the app from the runningApps list of that node.

Please also note that I have set this to patch available status so jenkins will
trigger.

> 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.
