Robert Metzger commented on FLINK-2960:
---------------------------------------
I would like to avoid doing the communication with YARN through the proxy by
fixing this issue similar to Hadoop:
https://issues.apache.org/jira/browse/FLINK-3074 (specifying an allowed
port-range).
Disadvantages of this approach:
- we would have two communication paths for RPC messages
- we would also need to send the blobs like this (or through HDFS, again two
communication paths)
The FLINK-3074 is MUCH easier to implement and will not completely mess up our
architecture.
I'm closing the issue as won't fix. Please reopen it if you disagree.

> Issue Type: Bug
> Components: YARN Client
> Affects Versions: 0.10.0

> In a secured environment, ports on the ApplicationMaster may be blocked.
