Subject [jira] Commented: (PIG-574) run command for grunt
Date Wed, 11 Feb 2009 17:58:59 GMT

    [ https://issues.apache.org/jira/browse/PIG-574?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12672699#action_12672699

Olga Natkovich commented on PIG-574:

Gunther, thanks for quick turnaround on the patch.

Is there a reason why we can't use exactly the same syntax on run/exec command for parameter
substituion as we do on Pig command line. I think that might be easier for users to remember
and provide a more consistent interface.

>             Project: Pig
>          Issue Type: New Feature
>          Components: grunt

>            Priority: Minor
>         Attachments: run_command.patch, run_command_params.patch
> 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.
