[HaoXuan40404]

my client can use namenode(like mkdir or ls), but cannot use datanode,(like download or upload), my network work right
this python code run right in centos and ubuntu，but failed with python 3.9 hdfs-2.6.0 macos12.3.1

if __name__ == '__main__':
    hdfs_client = HdfsApi()
    local_path = "./test_data.csv"
    print(hdfs_client.client.list('/'))
    print(hdfs_client.client.list('/ppc'))
    hdfs_path = "/root/LICENSE.txt"
    hdfs_client.get_dataset(hdfs_path, local_path)

when I run it, get

['ppc', 'root']
['LICENSE.txt']
