> LLAP: Replace Yarn registry with Zookeeper registry
> ---------------------------------------------------
>
> Key: HIVE-12935
> URL: https://issues.apache.org/jira/browse/HIVE-12935
> Project: Hive
> Issue Type: Bug
> Affects Versions: 2.0.0
> Reporter: Prasanth Jayachandran
> Assignee: Prasanth Jayachandran
> Attachments: 12935.1.patch
>
>
> Existing YARN registry service for cluster membership has to depend on
> refresh intervals to get the list of instances/daemons that are running in
> the cluster. Better approach would be replace it with zookeeper based
> registry service so that custom listeners can be added to update healthiness
> of daemons in the cluster.
