I don't know about the specific log policy here; but I do think using
reflection to get a private stuff is dangerous. I know it happens a lot in this
code but at some point it'd be nice to move it. you don't need to use
reflection to get the same log as a parent, just go
```
LoggerFactory.getLog("org.apache.hive.thrift...whatever").info(s"something
$key")
```
This is cleaner and not going to break if hive ever change logging
frameworks.
