Apache Drill 0.7 Errors

I have installed Apache Drill 0.7 on a small Community edition test cluster on EC2 in preparation for an Enterprise install. The install worked fine and all the drillbits are up and running.

However, when I try to run queries through sqlline things just hang.

 sqlline -u jdbc:drill:zk=ip-172-31-23-xxx.eu-west-1.compute.internal:5181
sqlline version 1.1.6
0: jdbc:drill:zk=ip-172-31-23-xxx.eu-west-1.c> show databases;

The above hangs forever.

In the log I find below error:
