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

             Summary: version_builder.py fails to run against Python 2.6
                 Key: AMBARI-16043
                 URL: https://issues.apache.org/jira/browse/AMBARI-16043
             Project: Ambari
          Issue Type: Bug
          Components: contrib
    Affects Versions: trunk
            Reporter: Di Li
             Fix For: trunk


version_builder.py uses the new xpath syntax only supported by ElementTree in Python 2.7 and newer. So running the example.py to invoke version_builder.py to create version XML fails with the following error when Python  is version 2.6.x

[root@myserver version-builder]$ python example.py
Traceback (most recent call last):
