-----------------------------------------

Check on RPC port of DataNode is not supported in Hadoop as of now. Until this
is added in Hadoop, such errors will be logged by DataNode alert process
Please create a Hadoop task for adding this support. I will keep this ticket
open in case if there is any other proposal apart from adding the support in
Hadoop.

Also this work doesn't seem to be feasible for 2.2.0 release. So moving this
out of 2.2.0
