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

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

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:
If I understand correctly. I think you need that if you need to pass value
to parameter in pig script in runtime. However, the value should be passed
in by "pig -param <param>=<value>" instead of "pig -p", Can you try that?

I guess maybe I was confused between the concept of parameter (as in
parameter substitution) and properties. I think I cleared it up now.
Thanks!
