> Remove dns.interface configuration options
> -------------------------------------------
>
> Key: HBASE-5587
> URL: https://issues.apache.org/jira/browse/HBASE-5587
> Project: HBase
> Issue Type: Improvement
> Affects Versions: 0.96.0
> Reporter: Eli Collins
>
> Are the {{hbase.*.dns.interface}} configuration options used or needed? Per
> HBASE-4109 it looks like these never really worked, at least in cases where
> the hostname with a trailing dot doesn't resolve. The reason I asked is that
> while these were introduced in Hadoop, I don't think they're actually used,
> nor am I convinced bypassing the host for DNS lookups is a good idea (leads
> to painful bugs where default Java DNS lookups differ with these lookups).
> HBase started using these via a similar feature in HBASE-1279 and HBASE-1279.
> I filed HADOOP-8156 to remove the API which HBase uses, which is obviously an
> incompatible change and would need to be worked around here if you wanted to
> keep this functionality in HBase, ie *if* that were to get checked into
> Hadoop we'd first need to get you on your own DNS class. Either way I'll
> update DNS' InterfaceAudience annotation to indicate HBase is a user.
