Subject [jira] [Updated] (HADOOP-11157) ZKDelegationTokenSecretManager never shuts down listenerThreadPool
Date Fri, 31 Oct 2014 02:33:34 GMT

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

Arun Suresh updated HADOOP-11157:
---------------------------------
    Attachment: HADOOP-11157.3.patch

Uploading new patch..

* I removed the Stat checks from the add/remove and delete method. I was thinking this should
be required.. If we agree that Each node will receive all node state changes (The Curator
framework gurantees that.. you can check the Path Cache code.. looks like on reregistering
with ZK after a watch.. it checks to see state change)

* I added another test case.. that test node shutdown and startup after sometime etc..

I also ran the test multiple times in a loop.. i dont see any errors..

> 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.
