Michel Tourn updated HADOOP-356:

    Attachment: nightlystreaming.patch

> Build and test hadoopStreaming nightly
> --------------------------------------
>          Key: HADOOP-356
>          URL: http://issues.apache.org/jira/browse/HADOOP-356
>      Project: Hadoop
>         Type: Improvement

> hadoopStreaming was originally built and tested separately.
> It makes sense to keep building the hadoopStreaming code as a separate jar file:
> this is all client code that can be uploaded in the Job jar.
> this allows quick turnaround on production clusters 
> (hadoopStreaming code updates do not require to bring down the MapReduce system.
> If necessary users can use their own modified versions of the hadoopStreaming jar but
still run on the production cluster.)
> On the other hand it makes sense to build this code nightly.
> Many recent changes broke either compilation or correctness.
> All the problems would have been caught if the hadoopStreaming compilation and tests
were run nighlty.
> Conclusion:
> the updated top-level build.xml adds the following dependencies:
> 1. Target compile calls target compile in contrib/streaming/build.xml
> 2. Target test calls target test in contrib/streaming/build.xml
