Arun Suresh updated HADOOP-11157:
---------------------------------
Attachment: HADOOP-11157.2.patch
Uploading new patch.
Summary of changes :
* Changed the listener threadpool to a SingleThreadedExecutor so that ZK watch
updates are always processed in the order it is received.
* add/update/delete of a token used to updated the localCache first and then
make changes in ZK. Changed this to ensure that localCache is always updated as
a result of a ZK notification.
* Fixed up the stopThreads to call super first
* During shutdown of AbstractDTSM, there can be calls to increment Delegation
token seqnum or KeyId.. which is a ZK operation now.. this used to result in an
InterruptedException which used to be thrown as a RuntimeException. This is now
caught and ignored (There is no possibility of an inconsistent state in ZK..)
I ran the test around 10 - 20 times in a loop.. Havnt seen an issue yet..
> 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.
