Commadline console output with the fix:
beeline> !typeinfo
No current connection
beeline> !nativesql
No current connection
> NullPointerException if typeinfo and nativesql commands are executed at
> beeline before a DB connection is established

> Before a DB connection is established, executing a command such as typeinfo
> and nativesql results an NPE shown at the console:
> beeline> !typeinfo
> java.lang.NullPointerException
> beeline> !nativesql
> java.lang.NullPointerException
> Instead, a message, such as "No current connection" should be given, as in
> case of some other commands, such as dropall.
