如何使用cm_api獲取get_yarn_applications

Question

我正在嘗試使用cm_api / get_yarn_applications獲取正在運行的YARN應用程序的列表。 我正在使用cm-api（9.0.0）和CM 5.3.2

我正在關注這個https://github.com/cloudera/cm_api/blob/master/python/src/cm_api/endpoints/services.py

lastHourDateTime = datetime.datetime.now（）-datetime.timedelta（小時= 1）

nowDateTime = datetime.datetime.now（）

yarn_applications = cm.get_service（）。get_yarn_applications（lastHourDateTime，nowDateTime）

但是我正在遵循異常

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib/python2.6/site-packages/cm_api/endpoints/services.py", line 418, in get_yarn_applications

如何使用filter_str獲取正在運行的紗線應用程序的列表

Answer 1

您需要在調用get_service()時指定YARN服務，並且要僅獲取正在運行的應用程序，您需要一個filter_str的state=RUNNING 。

如果您的YARN服務命名為yarn則您的get_yarn_applications()調用將類似於：

yarn_applications = cm.get_service("yarn").get_yarn_applications(lastHourDateTime, nowDateTime, filter_str = "state=RUNNING")
