[jira] [Created] (YARN-2314) ContainerManagementProtocolProxy can create thousands of threads for a large cluster

Jason Lowe created YARN-2314:
--------------------------------

             Summary: ContainerManagementProtocolProxy can create thousands of threads for a large cluster
                 Key: YARN-2314
                 URL: https://issues.apache.org/jira/browse/YARN-2314
             Project: Hadoop YARN
          Issue Type: Bug
          Components: client
    Affects Versions: 2.1.0-beta
            Reporter: Jason Lowe
            Priority: Critical


ContainerManagementProtocolProxy has a cache of NM proxies, and the size of this cache is configurable.  However the cache can grow far beyond the configured size when running on a large cluster and blow AM address/container limits.  More details in the first comment.
