> Project: ZooKeeper
> Issue Type: Bug
> Components: quorum
> Reporter: Raul Gutierrez Segales

> Fix For: 3.5.1, 3.6.0

> Attachments: ZOOKEEPER-2171.patch, ZOOKEEPER-2171.patch
>
>
> Apparently, ZOOKEEPER-107 (via a quick git-blame look) introduced a bunch of
> getHostName() calls in QCM. Besides the overhead, these can cause problems
> when mixed with failing/mis-configured DNS servers.
> It would be nice to reduce them, if that doesn't affect operational
> correctness.
