Is there any API for YARN & SPARK History Server in Cloudera Manager

KarthiK439 — Wed, 30 Sep 2020 16:31:44 GMT

Hi Team,

I want the list of all running yarn/spark applications along with the actual user name for the queries running with user as hive.

1) I was aware that we can use yarn application -list to get the list of running applications and

2) hive.access.subject.name in the configuration page of yarn history server/resource manager.

But for point#2, I need to manually check it for each application which is not a viable solution.

So, I was trying to check if there is any API available for YARN & SPARK history server to get the actual user of the query/application.

(OR)

It would great if we have any command to get the actual user name for a running application.

Kindly let me know if any additional information required.

Hello @KarthiK439 ,

You can get the list of Yarn Applications using the below API

Let me know if this is what you are looking for.

Thanks for your response @tjangid

This was something informational but unfortunately this is not what I was looking for.

Anyways, since I didn't find any API earlier, I have used urllib2 command and connected to History Server directly and then used some regexp's to extract the required content which is (hive.access.subject.name)
