Thanks for making this change. Considering that there is at least one more
system where this problem shows up, I suggest that we add an evnironment
variable check, something like sqoop.use.mkfifo, which if set turns this
behavior.

bq. Testing
bq. -------
bq.
bq. No new tests as the functionality is covered by an existing unit test. I
ran the existing unit test and it worked. I don't have a Mac to test on right
now, so it might be good to run the unit tests on one before commit.
