Review comment:
Oh wow. That existing code seems very broken. I'm fine with following
suit with what the rest of the code does and fixing it later. It's especially
concerning that we completely ignore the value in the Hadoop config when it's
set there, and use our property when it's not set there. I'm not sure why we
even bothered to read the value from the Hadoop config at all in that case, if
it has no bearing on what we're going to do.
