Ashutosh Chauhan updated PIG-796:
---------------------------------

    Attachment: 796.patch

updated patch.

This patch fixes the following issue: Sometimes (e.g. when values coming out of map lookup) Pig assumes type of element as ByteArray when actually it is of some other type. In such cases request for a Cast fails. 

This patch first finds out the actual type of element before casting it (specifically when Pig thinks its ByteArray) and then do the cast. It also caches the type. When type changes ClassCastException is raised which gets caught and cast is then tried again. Cached value of type is also updated. This ensures that type is not determined on each cast call as well as handling of casts when types changes from one call to the next.
