John Francis Unson updated HELIX-504:
-------------------------------------

    Sprint: Scrumban #2

> Controller should avoid resetting watches on removed paths
> ----------------------------------------------------------

>                 Key: HELIX-504
>                 URL: https://issues.apache.org/jira/browse/HELIX-504
>             Project: Apache Helix
>          Issue Type: Bug
>            Reporter: Kanak Biscuitwala
>
> Right now, if a participant has a session change, the old current state will 
> be removed, but the controller despite unregistering the listener, still 
> reset the watch on the path deleted event. We should avoid resetting this 
> path on delete and let the controller explicitly set watches/listeners on new 
> sessions.
