SteNicholas opened a new pull request #15873:
URL: https://github.com/apache/flink/pull/15873
## What is the purpose of the change
*Batch jobs don't need a checkpointing page, because there is no information
for these jobs available there. Therefore runtime web should hide the
checkpointing page in the UI.*
## Brief change log
- *The field `plan` of the response for `/jobs/:jobid` Rest API adds the
`type` field which represents the job type of the job graph to identify whether
the type of this job is `STREAMING` or `BATCH`.*
- *`job-status.component.ts` hides the checkpointing page through checking
the job type for the response of `/jobs/:jobid` Rest API.*
## Verifying this change
- *`JsonGeneratorTest` and `JsonJobGraphGenerationTest` add the validation
whether the `type` field value is equal to the job type of the job graph.*
