[jira] [Created] (MAPREDUCE-3138) Allow for applications to deal with MAPREDUCE-954

Allow for applications to deal with MAPREDUCE-954
-------------------------------------------------

                 Key: MAPREDUCE-3138
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-3138
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: client, mrv2
    Affects Versions: 0.23.0
            Reporter: Arun C Murthy
            Assignee: Owen O'Malley
            Priority: Blocker
             Fix For: 0.23.0


MAPREDUCE-954 changed the context-objs api to interfaces. This breaks Pig. We need a bridge for them to move to 0.23.

Konstantin Shvachko commented on MAPREDUCE-3138:
------------------------------------------------

Arun, thanks for the tip.
Do you plan to remove {{org.apache.hadoop.mapreduce.task.JobContextImpl}} from trunk and 0.23. Or is it some Pig build magic that excludes the package from the classpath?
Otherwise I don't understand how this patch distinguishes between 0.21 and 0.23.

I assume this patch doesn't fix Pig-0.8 issues with 0.22 and is targeted to 0.9 and later?

0.22 version of the patch is being validated by BigTop's build for 0.22 stack to make sure that it solved the problem there.

[jira] [Commented] (MAPREDUCE-3138) Allow for applications to deal with MAPREDUCE-954

Robert Joseph Evans commented on MAPREDUCE-3138:
------------------------------------------------

I am not positive of the intention of this patch.  It provides a bridge where pig can potentially compile against both 0.22 and 0.23 but it does not fix any binary compatibility issues.  Pig and Pig loader/storer UDFs compiled against pre-0.21 will need to be recompiled to work on 0.22 and 0.23.  The Java linker will throw an error if a class was compiled against a class and sees an interface with the same name or vise versa.  If the intention is not to provide binary compatibility we really need a JIRA to do that.  We have too many customers that are going to mutiny if they have to maintain two different binary versions of the same code to run on different grids.

Roman Shaposhnik commented on MAPREDUCE-3138:
---------------------------------------------

First of all, I'm really happy to see a move towards helping the downstream clients migrate to .23 smoothly. That said,
I'm not quite sure what is the intent of the patch. It would be very nice to have a clear description of what is it trying to accomplish. As it stands now, I can't really build Pig/Hive (or anything else for that matter) against .23 nor can I run the older binaries. Has this patch been tested?
