Subject [jira] Updated: (PIG-574) run command for grunt

Gunther Hagleitner updated PIG-574:
-----------------------------------

    Attachment: run_command_params_021109.patch

Good point. I felt it was a little strange to specify "-param" on the grunt shell, but it
is easier to remember if your using it outside the shell already.

So, this patch does the same as the last one, but the syntax is:

run myscript.pig -param LIMIT=5 -param FILE=/foo/bar.txt -param_file myparams.ppf

> run command for grunt

> This is a request for a "run file" command in grunt which will read a script from the
local file system and execute the script interactively while in the grunt shell.
> One of the things that slows down iterative development of large, complicated Pig scripts
that must operate on hadoop fs data is that the edit, run, debug cycle is slow because I must
wait to allocate a Hadoop-on-Demand (hod) cluster for each iteration.  I would prefer not
to preallocate a cluster of nodes (though I could).
> Instead, I'd like to have one window open and edit my Pig script using vim or emacs,
write it, and then type "run myscript.pig" at the grunt shell until I get things right.
> I'm used to doing similar things with Oracle, MySQL, and R.
