python-client problem

[akira822]

Alluxio Version:
2.9.3

Describe the bug
当我在python中使用alluxio第三方库，alluxio==0.1.3，当我运行以下代码时出现错误
file_id = self.client.open_file(video_path) reader = self.client.read(file_id) # 解码reader二进制流 video_stream = BytesIO(reader.read())
出现错误
requests.exceptions.jsondecodeerror: expecting value: line 1 column 1 (char 0)
完整错误信息为
File "/home/lj/anaconda3/envs/lgqopensora/lib/python3.10/site-packages/alluxio/client.py", line 410, in open_file
return self._post(url, opt).json()
File "/home/lj/anaconda3/envs/lgqopensora/lib/python3.10/site-packages/requests/models.py", line 975, in json
raise RequestsJSONDecodeError(e.msg, e.doc, e.pos)
requests.exceptions.JSONDecodeError: Expecting value: line 1 column 1 (char 0)
python-BaseException
但当我使用alluxio的版本为2.4.0时，就不会出现这个问题，我想问一下为什么？

What is "alluxio==0.1.3"? This is a so old version. Can you give me a link? Actually current version is 2.9.3 and 3.1.x.

[akira822]

I mean my python library is 0.1.3. Alluxio version is 2.9.3

我想问一下，当前最新版本的python客户端是必须使用ETCD服务吗？alluxio版本2.9.3，使用最新的python客户端，必须使用ETCD服务吗？

[YichuanSun]

No, alluxio 2.9.3 python client doesn't use ETCD.
