Colin Patrick McCabe commented on HDFS-7527:
--------------------------------------------
I am -1 for removing this test right now, until we understand this issue
better. Putting "registration names" in the host include and exclude files
used to work. If it stopped working, then that's a bug that we should fix.
Or, alternately, we should have a JIRA to remove registration names entirely.
Last time we proposed that, it got rejected, though. See HDFS-5237.
One example of where you might want to set registration names is if you're on
an AWS instance with internal and external IP interfaces. On each datanode,
you would set {{dfs.datanode.hostname}} to the internal IP address to ensure
that traffic flowed over the internal interface, rather than the (expensive)
external interfaces. In this case, you should be able to specify what nodes
are in the cluster using these same registration names, even if doing reverse
DNS on the datanode hostnames returns another IP address as the first entry.
