Fixes huggingface#2532 When a worker sends a heartbeat immediately after job assignment, it may race with job persistence, resulting in: `JobDocument matching query does not exist`. This patch adds retry logic to the `WorkerExecutor.heartbeat()` method in `executor.py`, retrying the heartbeat a few times (with delay) if this specific error occurs. This avoids false negatives and unnecessary worker shutdowns on transient states. Retries: 6 attempts Delay: 0.5s between retries Only the specific "JobDocument not found" error is retried — other exceptions still raise immediately.
