>
> Over in HBASE-1675, JSharp has posted logs where a temporary DNS outage does
> his cluster a death blow.
> When cluster members report in, the master composes the regionserver name by
> doing a hostname lookup and appending it to port and startcode passed over by
> the regionserver. The host lookup during a DNS outage when from name to IP.
> Master then thought this regionserver an unknown host and told it restart....
> and so on.
> If the regionserver composed its name once, it could pass this the master and
> avoid a DNS lookup per regionserver report.
