Vinayakumar B updated HDFS-9049:
--------------------------------
Attachment: HDFS-9049-04.patch
Thanks [~brahmareddy] for the review and suggestion.
I have changed the config name to *dfs.datanode.http.internal-proxy.port* (half
change from your suggestion :) ) to be inline with other http configs.
Test failures are unrelated. Fixed checkstyle comment too
> Make Datanode Netty reverse proxy port to be configurable
