> Swift driver should have a configurable retry feature when ecounter 5xx error
> -----------------------------------------------------------------------------

> Key: HADOOP-13211
> URL: https://issues.apache.org/jira/browse/HADOOP-13211
> Project: Hadoop Common
> Issue Type: New Feature
> Components: fs/swift
> Affects Versions: 2.7.2
> Reporter: Chen He
>
> 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.
