> Our Centos 6 builds use Python 2.6, which means that it doesn't have check_output (added in Python 2.7). This causes test failures in test_provider.py:
>  
> {noformat}
> authorization/test_provider.py:70: in setup_method
>     self.pre_test_cores = set([f for f in possible_cores if is_core_dump(f)])
> ../lib/python/impala_py_lib/helpers.py:64: in is_core_dump
>     file_std_out = exec_local_command("file %s" % file_path)
> ../lib/python/impala_py_lib/helpers.py:34: in exec_local_command
>     return subprocess.check_output(cmd.split())
> E   AttributeError: 'module' object has no attribute 'check_output'{noformat}
> This comes from the new code to handle intentional core dumps:
>  
> [https://github.com/apache/impala/blob/master/lib/python/impala_py_lib/helpers.py#L34]
> {noformat}
> def exec_local_command(cmd):
>   """  Executes a command for the local bash shell and return stdout as a string.
>   Args:
>     cmd: command as a string
>   Return:
>     STDOUT
>   """
>   return subprocess.check_output(cmd.split()){noformat}
