Jarek Jarcec Cecho commented on FLUME-1661:
-------------------------------------------
Well I can imagine that it might break backward compatibility on systems where
bash is not present or where it's not simple to get writable tmp directory. But
I guess that those are pathological cases that we do not have to take into
consideration.
