Robert Joseph Evans commented on MAPREDUCE-3211:
------------------------------------------------
The change looks good to me. I also don't know what the findbugs is talking
about. As for the tests you could update the some of the integration tests
that use the MiniMRYarnCluster to use an ephemeral port.
> Fetch failures if used ephemeral port for property "mapreduce.shuffle.port".
