[jira] [Created] (FLINK-17127) Make pod creating retry interval configurable

Yang Wang created FLINK-17127:
---------------------------------

             Summary: Make pod creating retry interval configurable
                 Key: FLINK-17127
                 URL: https://issues.apache.org/jira/browse/FLINK-17127
             Project: Flink
          Issue Type: New Feature
          Components: Deployment / Kubernetes
            Reporter: Yang Wang


Follow the discussion in this PR[1].

In the current implementation, the {{POD_CREATION_RETRY_INTERVAL}} is set to fixed value with "3s", which means when creating a taskmanager pod failed, we will schedule a delay retry in 3s. It could work for most cases. However, we still have a risk that too many retried of different Flink clusters will flood to Kubernetes api server. So we need to add an initial and max setting for retry interval, similar to {{NETWORK_REQUEST_BACKOFF_INITIAL/NETWORK_REQUEST_BACKOFF_MAX}}.
