Josh Elser commented on HBASE-14594:
------------------------------------
bq. Mind preparing patch for 0.98 - there are several rejected hunks ?
Not a problem, Ted! I'll give the other branches a look too. It's possible that
some of the intermediate branches had usages of {{DNS.getDefaultHost}} that
master no longer has. Will get to this tonight.
> Use new DNS API introduced in HADOOP-12437

> HADOOP-12437 introduced a new API to {{org.apache.hadoop.net.DNS}}:
> {{getDefaultHost(String, String, boolean)}}.
> The purpose of this method (the boolean argument really) is to change the
> functionality so that when rDNS fails, {{InetAddress#getCanonicalHostName()}}
> is consulted which includes resolution via the hosts file.
> The direct application of this new method is relevant on hosts with multiples
> NICs and Kerberos enabled.
> Sadly, this method only exists in 2.8.0-SNAPSHOT, so to benefit from the fix
> without great pain, some reflection is required.
