> If a user's map function is CPU intensive and doesn't read from the input
> very quickly, compounded by the buffering of input, then S3 might think the
> connection has been lost and will close the connection. Then when the user
> attempts to read from the input again, they'll receive a
> SocketTimeoutException and the task will fail.
