Review Request: Make Oozie compile against Hadoop 0.23

-----------------------------------------------------------

Review request for oozie, Tom White and Roman Shaposhnik.


Summary
-------

Make Oozie compile against Hadoop 0.23.

It depends on a few outstanding Hadoop JIRAs.

Everything compiles, testcases using MiniMR fail due to MAPREDUCE-3380.

This patch is a WIP


This addresses bug OOZIE-565.

JAR Injection, as until now can be done at build time, by using the -DincludeHadoopJars option or after installation.

Would be possible to share Mona's findings?


Given that using 0.23 is an optional profile, I'd like to commit this to trunk to facilitate work for Bigtop.

Thanks.

Looks very good.
 Want to clarify that jar injection will be done during runtime. not during packaging. right?

About running job successfully through Oozie: Mona has done it. But it needs some code changes in H 0.23. Not sure it was committed to hadoop trunk yet.

because here is the place we decide to bundle or not Hadoop dependencies in the distribution based on the includeHadoopJar profile, for other places is not required.

I noticed that you have used hadoop.jars.scope at webapp. Why not use it at other places as well?

Mona also faced the similar issue. doAs() is not working for Job submission. Hadoop uses the superuser (oozie) when submit MR job instead of the actual user. However, FileSystem looks ok.

Yes you can commit it and wait for the next hadoop patch. If oozie needs to be patched, we can create another JIRA.

Yes, i'm working on zeroing the issue in Hadoop side.

I'm for committing this and follow up if necessary once we identify the Hadoop issue.

Are you working on anything in this regard? Looks like the issue is no in Hadoop/MR core.
We can commit it and create another one when needed.

(Updated 2011-11-21 21:02:32.370561)


Review request for oozie, Tom White and Roman Shaposhnik.


Changes
-------

Patch rebased to trunk (after OOZIE-602 it was not applying).

It contains some minor (related) POM clean up (comments).

It changes 2 testcases to use the HadoopAccessor service (instead instantiating JobClient directly).

IMPORTANT: testcases are not passing as it seems proxyusers are not being honored by the new Mini MR.

Still, everything compiles.

As it is a non-default profile (0.23 is not used by default) I'd like to commit it and follow up with another JIRA in case the Mini MR issue requires tweaks in Oozie side.


Summary
-------

Make Oozie compile against Hadoop 0.23.

It depends on a few outstanding Hadoop JIRAs.

Everything compiles, testcases using MiniMR fail due to MAPREDUCE-3380.

This patch is a WIP


This addresses bug OOZIE-565.

Yes, it works fine with pre 0.23

1. 'includeHadoopJars' is for including the hadoop jars in the tar ball. right?

If we don't want to inject it during build. we can still inject that through 'addtowar'script. right? That mean hadoop 0.23 will still supports the 'addtowar.sh' based jar injection.

2. So profile 'mr2' is for place holder. by default 'mr1' is activated.

<https://reviews.apache.org/r/2778/#comment7481>

    Why it is required?
    How will it work on MR1?

Review request for oozie, Tom White and Roman Shaposhnik.


Changes
-------

v2 of the patch:

* corrections in the dependencies inclusions/exclusions.
* added 2 profiles mr1 (default, for pre 0.23) and mr2 (for 0.23+)
* the includeHadoopJars profile works correctly with both mr1 and mr2 profiles

I'm able to build Oozie (cannot run testcases yet). When running Oozie against Hadoop 0.23.FOO Oozie is able to submit jobs to Hadoop but the actions are failing. Have to see what wrong there.

Hadoop.23.FOO = Hadoop 0.23.0 + MAPREDUCE-3370 + MAPREDUCE-3169 + HADOOP-7590 + MAPREDUCE-3380


Summary
-------

Make Oozie compile against Hadoop 0.23.

It depends on a few outstanding Hadoop JIRAs.

Everything compiles, testcases using MiniMR fail due to MAPREDUCE-3380.

This patch is a WIP


This addresses bug OOZIE-565.
