--------------------------------
Target Version/s: (was: 3.1.1)
> Yarn Service Destroy: Delete service entries from Zookeeper in the
> ServiceMaster instead of ServiceClient in the RM
> -------------------------------------------------------------------------------------------------------------------
>
> Key: YARN-8402
> URL: https://issues.apache.org/jira/browse/YARN-8402
> Project: Hadoop YARN
> Issue Type: Sub-task
> Reporter: Chandni Singh
> Assignee: Chandni Singh
> Priority: Major
>
> RM slows down considerably when multiple services are destroyed
> simultaneously.
> 1. Started approx 1000 services
> 2. Destroyed all the 1000 services.
> Observed considerable slowness in RM after this.
> The {{ServiceClient}} in RM uses the {{CuratorClient}} to delete zookeeper
> entries.
> The zookeeper client is the bottleneck and this could be avoided if the
> zookeeper entry can be deleted from the AM and then the {{ServiceClient}} can
> kill the app.
