我正在安装pydoop(https://crs4.github.io/pydoop/installation.html)在centos 6上（hortonworks hdp物理集群，4个节点）。我的主机上安装了Python3.4和Python2.6。当我使用Python3安装它时，它会显示如下语法错误：

[root@abc]# python3 setup.py build
  File "setup.py", line 45
print 'using setuptools version', setuptools.__version__
                               ^
SyntaxError: Missing parentheses in call to 'print'

当我使用python2安装它时，它显示以下错误

[root@abc]# python setup.py build
using setuptools version 35.0.2
Traceback (most recent call last):
  File "setup.py", line 65, in <module>
    import pydoop
  File "/root/pydoop/pydoop/__init__.py", line 42, in <module>
   _HADOOP_INFO = _PATH_FINDER.find()  # fill the cache ASAP
  File "/root/pydoop/pydoop/hadoop_utils.py", line 624, in find
  info[a] = getattr(self, a)()
  File "/root/pydoop/pydoop/hadoop_utils.py", line 433, in hadoop_home
_hadoop_home_from_version_cmd() or
  File "/root/pydoop/pydoop/hadoop_utils.py", line 394, in          
_hadoop_home_from_version_cmd
output = sp.check_output([hadoop_exec, 'version'])
AttributeError: 'module' object has no attribute 'check_output'

我不想将默认python从2.6升级到2.7，因为它可能会破坏使用python2.6的yum，升级它可能会导致问题。有什么建议吗？
