I'm running a SegmentCreationAndTarPush batch ingest that has outputDirURI as a path on S3. I notice that if I drop the table, re-create the table, and run the batch ingest job again with different data (a different inputDirURI), it still ends up pushing all of the old data from the previous batch ingest job. Is this expected? Is there some way I can prevent it from happening?
