             Summary: Add the IP address if we enable debug for org.apache.drill.exec.coord.zk
                 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.
