> Add a way to register long-lived services in a YARN cluster
> -----------------------------------------------------------
>
> Key: YARN-913
> URL: https://issues.apache.org/jira/browse/YARN-913
> Project: Hadoop YARN
> Issue Type: New Feature
> Components: api, resourcemanager
> Affects Versions: 2.5.0, 2.4.1
> Reporter: Steve Loughran
> Assignee: Steve Loughran
> Attachments: RegistrationServiceDetails.txt
>
>
> In a YARN cluster you can't predict where services will come up -or on what
> ports. The services need to work those things out as they come up and then
> publish them somewhere.
> Applications need to be able to find the service instance they are to bond to
> -and not any others in the cluster.
> Some kind of service registry -in the RM, in ZK, could do this. If the RM
> held the write access to the ZK nodes, it would be more secure than having
> apps register with ZK themselves.
