> For batch shuffle(i.e. hybrid shuffle & sort-merge shuffle), If there is a fierce contention of the batch shuffle read memory, it will throw a {{TimeoutException}} to fail downstream task to release memory. But for hybrid shuffle, It uses an incorrect default timeout(5ms), this will make the job very easy to fail.
