viirya opened a new pull request #17582:
URL: https://github.com/apache/flink/pull/17582
## What is the purpose of the change
When creating Flink session cluster on K8S, Flink job manager won't create
configmap for the Hadoop configuration stored in the Docker image.
Then when users submit Java application, the task manager Pods will not be
abled to created, because it fails to mount the expected configmap of Hadoop
configuration. This leads to a weird error and hard to understand for (new)
Flink users.
This patch tries to fix this issue. So Flink users can include Hadoop
classes and configuration in Docker image.
## Brief change log
- *Create resouces for task manager Pods*
## Verifying this change
This change can be verified as follows:
- *Manually verified the change by running a 6 node cluser with 1
JobManagers and 5 TaskManagers from a Docker image including Hadoop deps and
configurations, a stateful streaming program, and verifying that TaskManage
Pods can be created with Hadoop configmap.
