Subject [jira] Created: (PIG-1588) Parameter pre-processing of values containing pig positional variables ($0, $1 etc)

Parameter pre-processing of values containing pig positional variables ($0, $1 etc)
-----------------------------------------------------------------------------------

                 Key: PIG-1588
                 URL: https://issues.apache.org/jira/browse/PIG-1588
             Project: Pig
          Issue Type: Bug
          Components: impl
    Affects Versions: 0.7.0
            Reporter: Laukik Chitnis
             Fix For: 0.7.0


Pig 0.7 requires the positional variables to be escaped by a \\ when passed as part of a parameter
value (either through cmd line param or through param_file), which was not the case in Pig
0.6 Assuming that this was not an intended breakage of backward compatibility (could not find
it in release notes), this would be a bug.

For example, We need to pass
INPUT=CountWords(\\$0,\\$1,\\$2)

instead of simply
INPUT=CountWords($0,$1,$2)
