cm_api.api_client.ApiException: (error 404)

一开始是这样遇到时，根据 https://blog.csdn.net/joomlaer/article/details/50073669 处理还是有错 

api = ApiResource(cm_host, cm_port, version=1, username="admin", password="***")

结果 

Traceback (most recent call last):
  File "hdfs.py", line 37, in 
    Test()
  File "hdfs.py", line 29, in Test
    result = api.query_timeseries(query, from_time, to_time)

访问的cm地址  http://host:port/api/version 

找到CDH版本所对应的api版本，修改version参数

api = ApiResource(cm_host, cm_port, version=12, username="admin", password="***")

搞定
