Olga Natkovich resolved PIG-1588.
---------------------------------
Resolution: Duplicate
This is duplicate of https://issues.apache.org/jira/browse/PIG-1586 and at this
point we do not believe that either is a bug in pig. Viraj is verifying that
but we think that shell removes the escapes before giving it to Pig
> 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)
