Chen He commented on HADOOP-13211:
----------------------------------
Thank you for the update, [[email protected]]. If we want to avoid data loss
on retry. How about recursive retry ? It looks little bit ugly but won't fail.
For object store server dead case, recursive is nightmare.
> Swift driver should have a configurable retry feature when ecounter 5xx error

> In current code. if Swift driver meets a HTTP 5xx, it will throw exception
> and stop. As a driver, it will be more sophisticate if it can retry a
> configurable times before report failure. There are two reasons that I can
> image:
> 1. if the server is really busy, it is possible that the server will drop
> some requests to avoid DDoS attack.
> 2. If server accidentally unavailable for a short period of time and come
> back again, we may not need to fail the whole driver. Just record the
> exception and retry may be more flexible.
