Review comment:
I guess things will fail with logging exception in caller site, so I guess
the recommendation is just removing try/catch altogether.
Hive source code has to do something (like wrapping as you've seen) because
both `LoginException` and `IOException` are checked exceptions - given you're
coding in Scala you can forget about that.
