> Project: Flink
> Issue Type: Improvement
> Components: YARN Client
> Reporter: Robert Metzger
> Assignee: Robert Metzger
> Fix For: 1.0.0
>
>
> Similar to the BlobServer, the YARN ApplicationMaster should allow starting
> it on a specified list or range of ports.
> In cases where only certain ports are allowed by a firewall, users can
> specify a range of ports where they want the AM to allocate its RPC port
