Description

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

This can be worked around with a combination of

• .setAddress(address)

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