Project: Pig
Issue Type: Bug
Components: grunt
Affects Versions: 0.3.0
Reporter: Viraj Bhat
Attachments: inputfile.txt, localparamsub.pig
I have a script in which I do a parameter substitution for the input file. I
have a use case where I find it difficult to debug based on the error
messages in local mode.
{code}
A = load '$infile' using PigStorage() as
(
date: chararray,
count : long,
gmean : double
);
dump A;
{code}
1) I run it in local mode with the input file in the current working directory
{code}

Thanks. Didn't know about the dry-run option.
Hopefully it will someday produce UTF-8 text given some of the parameters will
be in Chinese or Japanese characters. :^)

Viraj Bhat commented on PIG-755:
Ciemo presently there is an option in Pig known as dryrun or '-r', where it
produces a pigscript.substituted in ASCII text in which it replaces all the
parameters with actual values..
