ZK registry entries cleanup for slider app

New Contributor

Hi,

Setup - slider version .80, secure hadoop cluster, registry enabled with security.

Noticed using *** zookeeper client (zkCli.sh) *** that when slider application is stopped, the registry entries in zookeeper /registry/users/xxx/services/org-apache-slider/abc/components do not get deleted. However, they do get updated when application is started again and new container IDs get allocated. In this case, the components/containers_ do reflect new container IDs. Also noticed that ZK registry entries do get deleted if "destroy" applications is done.

Is this expected behavior ? Shouldn't the ZK entries be deleted when application and its containers are not present after application is stopped ?

Thanks in advance,

Manoj
