-------------------------------------

             Summary: S3A typo in pom.xml test exclusions
                 Key: HADOOP-14087
                 URL: https://issues.apache.org/jira/browse/HADOOP-14087
             Project: Hadoop Common
          Issue Type: Sub-task
          Components: fs/s3
    Affects Versions: HADOOP-13345
            Reporter: Aaron Fabbri
            Assignee: Aaron Fabbri


When you overload DDB, you get error messages warning of throttling, [as documented by AWS|http://docs.aws.amazon.com/amazondynamodb/latest/developerguide/Programming.Errors.html#Programming.Errors.MessagesAndCodes]

Reduce load on DDB by doing a table lookup before the create, then, in table create/delete operations and in get/put actions, recognise the error codes and retry using an appropriate retry policy (exponential backoff + ultimate failure)
