--------------------------------
Summary: 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
Assignee: 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.
