Hi all,

thanks,

> NodeListManager has a memory leak, unusableRMNodesConcurrentSet is never
> purged
> -------------------------------------------------------------------------------
>
> Key: YARN-1382
> URL: https://issues.apache.org/jira/browse/YARN-1382
> Project: Hadoop YARN
> Issue Type: Bug
> Components: resourcemanager
> Affects Versions: 2.2.0
> Reporter: Alejandro Abdelnur
>
> If a node is in the unusable nodes set (unusableRMNodesConcurrentSet) and
> never comes back, the node will be there forever.
> While the leak is not big, it gets aggravated if the NM addresses are
> configured with ephemeral ports as when the nodes come back they come back as
> new.
> Some related details in YARN-1343
