Dmitry Sivachenko commented on HADOOP-10797:
--------------------------------------------

Okay, I see.  The point to use /bin/sh is that most of these shell scripts are very simple and do not require any bash-specific things.  And since there are systems that do not ship bash by default, this would eliminate one extra dependency.  But it is not a big deal if you prefer to stick with more heavyweight bash instead.

> Most of shell scripts use shebang ling in the following format:
> #!/usr/bin/env bash
> But some scripts contain hardcoded "/bin/bash" which is not portable.
> Please use #!/usr/bin/env bash instead for portability.
> PS: it would be much better to switch to standard Bourne Shell /bin/sh, do these scripts really need bash?
