python连接hdfs常用操作

import contextlib

import pyhdfs

fs = pyhdfs.HdfsClient(hosts='name-node1:9870,name-node2:9870', user_name='hdfs')
response = fs.open('/tmp/README.txt')
#读
response.read()
response.readline()
response.seek()
with contextlib.closing(fs.open('/fruit/apple')) as f:
    f.read()
#写
fs.append("/user/hadoop/test.csv", "0,2,0

")
#本地导入导出hdfs
fs.copy_from_local('/opt/test/wangbin/addr.py', '/tmp/addr.py')
fs.copy_to_local('', '')
#目录操作
fs.listdir("/user/hadoop/")
fs.mkdirs()
fs.exists('/path')
fs.delete('')
fs.delete('',recursive=True)
