[jira] [Commented] (PIG-2122) Parameter Substitution doesn't work
in the Grunt shell
[ https://issues.apache.org/jira/browse/PIG-2122?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13464326#comment-13464326 ]
Joshua Hartman commented on PIG-2122:
-------------------------------------
This irritates me on a weekly basis. I'm often running ad-hoc analysis in grunt with snippets taken from some heavier scripts I've written and I get bitten ALL the time.

> Simple param substitution and things like %declare (as copied out of the docs) don't work in the grunt shell.
> #Start Pig with: Start Pig with: bin/pig -x local -p time=FOO
