Description

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

foo = LOAD '/user/grant/foo.txt' AS (a:chararray, b:chararray, c:chararray);
Y = foreach foo generate *, '$time';
dump Y;

Output:

2011-06-13 20:22:24,197 [main] INFO org.apache.pig.backend.hadoop.executionengine.util.MapRedUtil - Total input paths to process : 1
(1 2 3,,,$time)
(4 5 6,,,$time)

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

(1 2 3,,,FOO)
(4 5 6,,,FOO)

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