Vinod Kumar Vavilapalli commented on HADOOP-3145:
-------------------------------------------------
Thinking more about the interface, and re-reading what is earlier said(Arkady
over mail to Hemanth) - "it is more generally assumed that -s option can take
command, and not a file name". If that is the case, it makes more sense to have
it done through the script sub-command itself. That would also mean adding no
extra sub-commands, as well as using the code already in place.
As a aside, if we go with this, can hod.cmd also be a series of
commands(separated by a semi-colon), and not just a single command ? Note that
this is not an implementation detail, it is about how hod interface will be
used; if series of commands is how users use it in general, then there will be
redundant ways of doing it - a script file or via hod.cmd.

> Project: Hadoop Core
> Issue Type: Bug
> Components: contrib/hod
> Affects Versions: 0.16.0
> Reporter: Arkady Borkovsky
> Assignee: Vinod Kumar Vavilapalli
> Fix For: 0.16.3
>
>
> The current version allows only to specify a "script".
> So if one needs to generate a single command, one has to create a file for
> this, which very inconvenient -- generating temp file name, printing,
> deleting the file.
> It also incompatible with hod 0.3
