Adam Szita commented on PIG-5132:
---------------------------------

[~kellyzly]: there are still a lot of differences that your patch doesn't have. 
I only listed some examples before, not the whole list, see 
[^diffOfPatches.png].
Here:
-blue means diff in the file
-black denotes missing files from your side
-green means files that should be deleted but are still present on your side
You can see that throughout ivy, documentation, hadoop-streaming and other 
locations there is still differences to be pulled from trunk into your patch.

So your recent patch (PIG-5132.2.fix.patch) only fixes 4 problems and I don't 
think it is worth to fix every little issue one-by-one manually.
I still think you should revert the committed patch, and *git apply 
PIG-5132.1.patch*. After this you have to *git apply PIG-5132.1_fixes.patch* as 
I wrote in the steps above.
The reason why I placed two diffs is:
PIG-5132.1.patch: merge_from_trunk diff (but this is not necessarily results in 
a build-able Pig code base)
PIG-5132.1_fixes.patch: takes care of necessary changes on spark branch side to 
follow trunk properly (e.g. removing SparkMiniCluster.java from hadoop20, 
moving SparkMiniCluster from hadoop23 under pig/test directory

If you apply these patches after each other (using git apply) hadoop20 and 
hadoop23 dirs get removed from shims because git doesn't keep empty directory 
structures.
