-----------------------------------

             Summary: inability to run Drill under certain networking conditions
                 Key: DRILL-1856
                 URL: https://issues.apache.org/jira/browse/DRILL-1856
             Project: Apache Drill
          Issue Type: Improvement
          Components: Execution - RPC
         Environment: OSX on wifi away from the office
            Reporter: Chris Westin


At the office, Drill starts up fine, but when running it from home, I get an exception when
it tries to start up the (embedded) drill bit:

java.net.UnknownHostException: wormsign.domain: wormsign.domain: nodename nor servname provided,
or not known
	at java.net.InetAddress.getLocalHost(InetAddress.java:1473)
	at org.apache.drill.exec.service.ServiceEngine.start(ServiceEngine.java:62)

This can be worked around with a combination of

diff --git a/exec/java-exec/src/main/java/org/apache/drill/exec/service/ServiceEngine.java
b/exec/java-exec/src/main/java/org/apache/drill/exec/service/ServiceEngine.java

and commenting out the line that calls InetAddress.getLocalhost()..... -- that's where the
exception is coming from for me.
