Sounds reasonable. Updated PR.

> Key: DRILL-4523
> URL: https://issues.apache.org/jira/browse/DRILL-4523
> Project: Apache Drill
> Issue Type: Improvement
> Components: Server
> Affects Versions: 1.6.0
> Reporter: Arina Ielchiieva
> Assignee: Arina Ielchiieva
> Fix For: 1.7.0
>
>
> If we enable debug for org.apache.drill.exec.coord.zk in logback.xml, we only
> get the hostname and ports information. For example:
> {code}
> 2015-11-04 19:47:02,927 [ServiceCache-0] DEBUG
> o.a.d.e.c.zk.ZKClusterCoordinator - Cache changed, updating.
> 2015-11-04 19:47:02,932 [ServiceCache-0] DEBUG
> o.a.d.e.c.zk.ZKClusterCoordinator - Active drillbit set changed. Now
> includes 2 total bits. New active drillbits:
> h3.poc.com:31010:31011:31012
> h2.poc.com:31010:31011:31012
> {code}
> We need to know the IP address of each hostname to do further troubleshooting.
> Imagine if any drillbit registers itself as "localhost.localdomain" in
> zookeeper, we will never know where it comes from. Enabling IP address
> tracking can help this case.
