> The logging for QueryResultsCache ends up printing information without
> context, like
> {code}
> 2018-06-30T17:48:45,502 INFO [HiveServer2-Background-Pool: Thread-166]
> results.QueryResultsCache: Waiting on pending cacheEntry
> {code}
> {code}
> 2018-06-30T17:50:17,963 INFO [HiveServer2-Background-Pool: Thread-145]
> ql.Driver: savedToCache: true
> {code}
> The previous lines for this are in DEBUG level, so the logging ends up being
> useless at INFO level to debug.
