JDBC and ODBC connectivity issues and DNS name resolution

A quick note for others who may run into this issue.

Using ZooKeeper for connectivity to drillbit(s) require that the client system can resolve the hostname of the ZK node(s). This either requires DNS name resolution or entries in the hosts file of the client system.

Drill clusters (and the MapR Drill sandbox) require this if JDBC or ODBC connections are established to a ZK quorum.

The documentation now also reflects this requirement.
