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

             Summary: Kudu python module should not require unittest2
                 Key: KUDU-1456
                 URL: https://issues.apache.org/jira/browse/KUDU-1456
             Project: Kudu
          Issue Type: Improvement
          Components: python
    Affects Versions: 0.8.0
            Reporter: Casey Ching


Trying to use the python client on centos 6 fails if unittest2 isn't installed

 line 34, in <module>
23:22:04     import unittest2 as unittest
23:22:04 ImportError: No module named unittest2
{noformat}

compat.py:

{code}
if PY26:
    import unittest2 as unittest
else:
    import unittest
{code}

Any testing-only modules shouldn't be required. Moving them to something like 
"test_compat.py" would be nice.
