stack commented on HBASE-19394:
-------------------------------

Thanks [~brfrn169] Was thinking of removing this facility because it so little used and exotic
too. You don't know how it is being used by your customer sir? Thanks.

> Currently, when the publication feature is enabled (hbase.status.published=true), it
uses the interface which is found first:
> https://github.com/apache/hbase/blob/2e8bd0036dbdf3a99786e5531495d8d4cb51b86c/hbase-server/src/main/java/org/apache/hadoop/hbase/master/ClusterStatusPublisher.java#L268-L275
> This won't work when the host has the multiple network interfaces and the unreachable
one to the other nodes is selected. The interface which can be used for the communication
between cluster nodes should be configurable.
