> We've recently started to see duplicate logs in S3. After digging into it, we discovered that this was due to our use of the new `reschedule` mode on our sensors. Because the same `try_number` is used when a task reschedules, the local log file frequently contains results from previous attempts. Additionally, because the `s3_task_helper.py` always tries to `append` the local log file to the remove log file, this can result in massive logs (we found one that 400 mb).
> To fix this, we'd like to remove the local log after a successful upload.
