Karthik Kambatla commented on HADOOP-11157:
-------------------------------------------
Thanks for working on this, Greg.
Couple of minor comments: Can we wait for a timeout after shutdown? Also, it
would be nice to have a unit test.
> ZKDelegationTokenSecretManager never shuts down listenerThreadPool

> 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.
