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.
