大数据Hadoop工具python教程２-python访问HDF

https://pypi.org/project/hdfs3　已经不维护
PyArrow
https://pypi.org/project/hdfs/
https://pypi.org/project/snakebite/　python2中比较好，对python3支持不好。

hdfs和PyArrow比较常用，这里以hdfs为例：

快速入门

from hdfs import InsecureClient
client = InsecureClient('http://localhost:50070', user='hduser_')

fs_folders_list = client.list("/")
print(fs_folders_list)
with client.read('/user/hduser/input.txt', encoding='utf-8') as reader:
    for line in reader:
        print(line)

执行结果：

['user']
