Subject Re: hbase has problems with two hostname

Hi C R,

Like many Hadoop-like services, HBase is pretty temperamental about
requiring forward and reverse DNS to work properly. FWIW, the configuration
file where you can populate RegionServers doesn't tend to matter as long as
the hbase-site.xml file is populated correctly (it's just used to start
daemons from one place).

If you pass along more details about how exactly you're deploying HBase, we
might be able to give more advice.
