Description

Currently there are cases when beeline could print out pretty non informative error messages...

like:

java.sql.SQLException: Could not open client transport with JDBC Uri: jdbc:hive2://xxx:10000: null

which is okay most of the time; but I think we would need to add some --debug or something which sends the stacktrace also...because it's very hard to start troubleshooting a "null" message
