[jira] [Created] (YARN-1382) NodeListManager has a memory leak, unusableRMNodesConcurrentSet is never purged

Alejandro Abdelnur created YARN-1382:
----------------------------------------

             Summary: 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.
