Vinod Kumar Vavilapalli updated HADOOP-3023:
--------------------------------------------

    Attachment: HADOOP-3023

Attaching a patch. This removes the python version check from ant build.xml. This is moved to testing/main.py which is the entry point for running test cases.

ant test now runs the tests when it finds python of version 2.5.1 or greater specified through -Dpython.home. If it finds a lesser version, it fails with return code 1, and with proper message. In case of a particular test-case failing, testing/main.py returns an error code 2. It returns a 0 when all test-cases run successfully.

Also refactored code in testing/main.py

> To run the HOD pyunit tests, the build file checks that an exact python version is present:
> +      <condition property="python.versionmatched">
> +        <!--- Currently check for only 2.5.1 -->
> +        <equals arg1="${hodtest.pythonVersion}" arg2="Python 2.5.1" />
> +      </condition>
> This is too restrictive (we have 2.5.2 on our Solaris build machine).  I suggest that you don't check the python version and instead issue a warning message if the pyunit test fail stating that python 2.5.1 or great is required (and optionally showing them what version they tried to use).
