             Summary: Improve beeline to show exception backtrace on connection 
failure
                 Key: HIVE-20229
                 URL: https://issues.apache.org/jira/browse/HIVE-20229
             Project: Hive
          Issue Type: Bug
          Components: Beeline
            Reporter: Zoltan Haindrich


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

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

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
