["Daniel Dai (Updated) (JIRA)" <ji...@apache.org>]

Daniel Dai updated PIG-2317:
----------------------------

    Attachment: PIG-2317-8_plus.patch

I tried the latest patch. Find couple of issues in e2e tests in mapreduce mode. I attach PIG-2317-8_plus.patch on top of Jonathan's patch. Here is what I did:
1. The original patch ship way too much files to the backend, my job.jar is larger than 20G. I fix it by only ship necessary ruby files
2. ruby.jar will be registered automatically only when ruby UDF is used, same mechanism as jython UDF
3. drop the dependency of pigudf.rb on pig.jar. All pig classes is assumed to be in classpath
4. pigudf.rb will be shipped automatically if ruby UDF is used
5. bin/pig and e2e test changes to support the above changes

Other than these, patch looks good. +1 for commit once Julien's comments are addressed.
