Parameter Substitution doesn't work in the Grunt shell
------------------------------------------------------
Key: PIG-2122
URL: https://issues.apache.org/jira/browse/PIG-2122
Project: Pig
Issue Type: Bug
Affects Versions: 0.8.1, 0.8.0
Reporter: Grant Ingersoll
Priority: Minor
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
{quote}
foo = LOAD '/user/grant/foo.txt' AS (a:chararray, b:chararray, c:chararray);
Y = foreach foo generate *, '$time';
dump Y;
{quote}
Output:
{quote}

Same script, stored in junk.pig, run as: bin/pig -x local -p time=FOO junk.pig

Also, things like don't work (nor does %declare):
