> I'm working on a project that uses an {{ExecutorService}} to launch a bunch of threads.
 Each thread spins up an HDFS client connection.  At any point in time, the program can terminate
and call {{ExecutorService#shutdownNow()}} to forcibly close vis-à-vis {{Thread#interrupt()}}.
 At that point, I get a cascade of logging from the above code and there's no easy to way
to turn it off.
> "Log and throw" is generally frowned upon, just throw the {{Exception}} and move on.
