Enis Soztutar updated HADOOP-2690:
----------------------------------
Attachment: jar-test_v1.patch
bq. I took Enis to be suggesting that we break the "compile-core-test" target
in two, one with the 'javac' tasks and one with the 'jar' task. There are a
bunch of other tasks in "compile-core-test" that will need to be delt with too.
At a glance, I suspect most of these should remain in "compile-core-test" and
just the 'jar' task should be moved to the new task, jar-core-test. Then
dependencies need to be adjusted so that things still work.
Exactly !
This patch just does that. I named the target jar-test, not jar-core-test,
since the resulting jar file is named hadoop-test.jar. compile-core-test would
have been further divided into two, but i guess it is not necessary.

>
> In order to build Pig and run its unit tests with ant, Pig needs to be built
> and run against a hadoop jar file that not only has the MiniDFSCluster and
> MiniMRCluster classes but also has classes from several 3rd party libraries.
> I added a target to the build.xml file of Hadoop for that purpose (see the
> "Compile code for Pig" section in the attached build.xml). I also attached
> the resulted hadoop jar with this report.
