> With sensors using {{reschedule}} mode and {{S3TaskHandler}} for logging, the task instance log gets a bunch of duplicate messages. I believe this is happening because contents of the local log file are appended to what's already in S3. The local log file may contain log messages that have already been uploaded to S3 if the task is sent back to a worker that had already processed a poke for that task instance.
