I am not able to assign a value with spaces to param on command line.
$ pig -p cond='x == 1' test.pig
results in command line parser error.
other attempts like 'pig -p cond='"x == 1"' test.pig' didn't help.

Is there a work around?
otherwise I will file a jira and look into a fix.

thanks,
Raghu.

It's not the space, it is the '=' character which is not allowed. Use \ to
do the escape, cond="x \=\= 1".

This helps.. I was wondering why my test didn't work even when  there were
no spaces.

The space is still a problem. When there is a space it still causes
"2011-07-12 05:10:48,496 [main] ERROR org.apache.pig.Main - ERROR 2999:
Unexpected internal error. Encountered unexpected arguments on command line
- please check the command line."

to summarize :
  "x == 1" : does not work
  "x==1" : doesn't
  "x\=\=1" : does
  "x \=\= 1" : doesn't

Seems space works for me. You can use -r to dry-run the parameter
substitution part to see what it results.

are you using bin/pig? With bin/pig, it does not even go to substitution
stage. bin/pig joins all the arguments into one bash string.

If I explicitly invoke pig java command (as printed with -secredDebugCmd)
with the arguments it works. Btw, spaces before '=' also need to be escaped
looks like.

I am not using bin/pig, I am using pig.jar directly. Yes, I saw space before
'=' is strip out, feel free to open a Jira ticket.

https://issues.apache.org/jira/browse/PIG-2162

attached patch for bin/pig.

didn't fix Pig parser. Currently parsers for %default and -p seem different.
