[jira] [Created] (HADOOP-13259) mvn test runs to set DNS TTL to 20s

Steve Loughran created HADOOP-13259:
---------------------------------------

             Summary: mvn test runs to set DNS TTL to 20s
                 Key: HADOOP-13259
                 URL: https://issues.apache.org/jira/browse/HADOOP-13259
             Project: Hadoop Common
          Issue Type: Sub-task
          Components: fs/s3, test
    Affects Versions: 2.8.0
            Reporter: Steve Loughran
            Priority: Minor


S3 is faster and more resilient to failure if the DNS load balancing is queried regularly. This should be done in testing both for performance and to verify that frequent DNS refresh doesn't break things.
