运行"快速开始"的例子时出错

我的python环境是2.7.5，操作系统是redhat7.2，执行
pip install euler-gl
安装，在运行
https://github.com/alibaba/euler/wiki/%E5%BF%AB%E9%80%9F%E5%BC%80%E5%A7%8B
这个例子时，跑到
python ppi_data.py
这一步，报这个错误：

Traceback (most recent call last):
File "ppi_data.py", line 32, in
from euler.tools import json2dat
File "/usr/lib/python2.7/site-packages/euler/__init__.py", line 20, in

OSError: libhdfs.so.0.0.0: cannot open shared object file: No such file or directory

单机安装还需要配置hdfs么？

Start with the Quick Start wiki example and run `python ppi_data.py` in the reported Python 2.7.5 and Red Hat 7.2 environment. Trace the import from `euler.tools.json2dat` through `euler/python/service.py` to the `ctypes.CDLL` call, and verify whether the example can run without the reported `libhdfs.so.0.0.0` error.
