Hi, While reviewing StreamExecution and how batches are displayed in web UI, I've noticed that currentBatchId is -1 when StreamExecution is created [1] and becomes 0 when no offsets are available [2].
That leads to my question about setting the job description for a query using getBatchDescriptionString [3]. It branches per currentBatchId and when it's -1 gives "init" [4] which never happens as showed above. That leads to the PR for SPARK-20464 "Add a job group and description for streaming queries and fix cancellation of running jobs using the job group" that sets the job description after populateStartOffsets [5]. Shouldn't it be before populateStartOffsets so getBatchDescriptionString has a chance of giving "init" and we see no two 0s? Help appreciated.
