Subject [jira] [Updated] (HADOOP-11157) ZKDelegationTokenSecretManager never shuts down listenerThreadPool
Date Tue, 30 Sep 2014 23:56:33 GMT

     [ 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.
