I am trying to setup a drill cluster running 3 vm nodes running CentOS 7. I
have successfully installed a small zookeeper ensemble on the three nodes
and then installed drill as per the documentation. I am having trouble
connecting to the other drillbits when running drill-conf: However, this
issue is intermittent. I can eventually connect if I spam drill-conf.
Error: Failure in connecting to Drill:
org.apache.drill.exec.rpc.RpcException: CONNECTION :
java.nio.channels.UnresolvedAddressException (state=,code=0)
java.sql.SQLException: Failure in connecting to Drill:

users"
0: jdbc:drill:>
As I said, I will eventually connect only after spamming drill-conf a few
times.
In addition to this failure, I am unable to run broadcast joins when I
point my drill cluster to an external HDH datasource. This failure happens
100% of the time:
Error: CONNECTION ERROR: Error setting up remote intermediate fragment

Doing a grep on that error id I can see this error message:

I have spent the last week and half pulling my hair out. I've combed
through the documentations but cannot find any information about may
causing this. I am at this point in desperate need for help on this
problem. Any insight into what may be causing this would be met with
extreme gratitude. If I haven't provided enough documentation please
contact me as soon as possible.
Thank You
