Exposing Spark Driver and Worker stdout stderr logs in Kubernetes to History Server

5/6/2021

I'm using Spark 3.0.0 with Kubernetes master. I am using a cluster mode to rung the spark job. Please find the spark submit command as below

I have hosted a different pod running history server with the same image. The history server is able to read all the event logs and shows details. The job is executed successfully.

I do not see driver pod and worker pod's stdout and stderr logs in History server. How can I enable it?

Unfortunately, it appears that there is no way for the driver-scoped logs to be piped to the spark-submit scope. From the docs:

Logs can be accessed using the Kubernetes API and the kubectl CLI. When a Spark application is running, it’s possible to stream logs from the application using:

kubectl -n=<namespace> logs -f <driver-pod-name>
