Hi Kousuke, thanks for the patch!
I've made you a contributor, so now you should be able to assign Common JIRAs
to yourself and mark them as Patch Available via the "Submit Patch" button.
Part of the trickiness from removing "2>&1" is error handling. I haven't looked
into DF at all, but {{ProcessBuilder}} separates stdout and stderr, so stderr
messages no longer show up. So, I added another param to {{Shell}} in
HADOOP-9652 (hopefully committed soon) which merges them back together.
It'd be great if you can review the {{DF}} error handling behavior, especially
adding tests for any missing holes you find.

> {{DF}} uses "bash -c" to shell out to the unix {{df}} command. This is
> potentially unsafe; let's think about removing it.
