[CACHE 'dfs_path#dfs_file' , 'dfs_path#dfs_file' ...]

> mapreduce operator (PIG-506) and stream operator have some similarities. It makes sense
to use a similar syntax for both.
> Alan has proposed the following syntax for mapreduce operator, and that we move stream
operator also to similar a syntax in a future release.
> MAPREDUCE id jar
>          INPUT  'path' USING LoadFunc  
>         OUTPUT  'path' USING StoreFunc
>         [SHIP 'path' [, 'path' ...]]
>         [CACHE 'dfs_path#dfs_file' [, 'dfs_path#dfs_file' ...]]
