Eli Collins commented on HADOOP-8010:
-------------------------------------

The change is fine by me, I'm just trying to understand it.

The bug is that running the hadoop daemon commands hits this error, but given 
that the error should only hit when not using bash, and the hadoop daemons 
explicitly use bash, I suspect there's something else going on here. Eg is this 
because bash is a symlink to dash on debian?
