FAQ
Hi Johnny,
Actually it was a mistake on my part. I was writing some custom code
that launches Grunt and I had a call that passed my input through
ParameterSubstitutionPreprocessor when it may not need to be. I
haven't had a chance to thoroughly read that class. Do you know off
the top of your head what kind of functionality does this class
provide? Would I be correct in assuming it's normally not needed?

Hi, Jeff:
It works for me though. Can you paste the whole command?

Hi guys,

I'm running pig from the command line in local mode, and trying to
pass in some properties, for example:
pig -x local ... -p mapred.map.tasks=2 -p mapred.reduce.tasks=1 ...

I'm getting errors;
INFO parameters.ParameterSubstitutionPreprocessor: Encountered "
<OTHER> ".map.tasks=2 "" at line 1, column 7.
Was expecting:
"=" ...

My question is, what am I doing wrong? What's the correct way to pass
in the properties via command line arguments?

Thanks,
Jeff
