[jira] [Updated] (HADOOP-11157) ZKDelegationTokenSecretManager never shuts down listenerThreadPool

     [ https://issues.apache.org/jira/browse/HADOOP-11157?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Gregory Chanan updated HADOOP-11157:
------------------------------------
    Attachment: HADOOP-11157.patch

Here's a patch that addresses the issue.  I moved the listenerThreadPool to follow the same lifetime as the keyCache/tokenCache.  I'm not sure how to add a testcase because it is a thread leak; are there any existing tests that look for thread leaks?

> I'm trying to integrate Solr with the DelegationTokenAuthenticationFilter and running into this issue.  The solr unit tests look for leaked threads and when I started using the ZKDelegationTokenSecretManager it started reporting leaks.  Shuting down the listenerThreadPool after the objects that use it resolves the leak threads errors.
