[jira] [Created] (FLINK-29847) Store/cache JarUploadResponseBody

Daren Wong created FLINK-29847:
----------------------------------

             Summary: Store/cache JarUploadResponseBody
                 Key: FLINK-29847
                 URL: https://issues.apache.org/jira/browse/FLINK-29847
             Project: Flink
          Issue Type: Improvement
          Components: Kubernetes Operator
            Reporter: Daren Wong
             Fix For: kubernetes-operator-1.3.0


Kubernetes operator currently uploadJar always even when the same JAR has been uploaded to JM previously. For example, this occurs during rollback operation.

To improve the performance, we want to cache the JarUploadResponseBody so that in the next runJar operation, kubernetes operator will check the cache and reuse the jar if it's the same JAR. This "cache" can be as simple as storing the uploaded JarFilePath in the CR Status field.
