> Currently, default number of times we should retry errors is 20,  however, oss sdk retry
delay is       
> {code:java}
> long delay = (long)Math.pow(2, retries) * 0.3
> {code}
>  when one error occurs. So, if we retry 20 times, sleep time will be about 3.64 days
and it is unacceptable. So we should change the default behavior.
