> Issue Type: Bug
> Components: build
> Affects Versions: 0.8.0, 0.9.0
> Reporter: Araceli Henley
> Assignee: Richard Ding

> a = load '$in' using com.yahoo.grid.sath.JobHistoryLoader() as
> (job:map[],maps:bag{},reducers:bag{},other:bag{},conf:map[]);
> The pig script stored in: conf#'pig.script' has the whitespace removed, this makes it difficult to extract and run the
> script. In particular, statements that terminate in ";" work correctly as
> "statement1;statement2;statement99" but statements that do not end in ";" result in
> "statement1statement2statement3" and it's difficult to parse the pig script and fix the concatenated string.
> There's also a problem with comments as in:
> /*mycomment*//*more comments*/ PIG_CODE //comment PIG_CODE
> On a side note, I also noticed that in many of the scripts the last statement is missing ";"
