Chris Nauroth commented on HADOOP-13259:
----------------------------------------
[[email protected]], do you think we could achieve what you're describing by
setting the system properties related to DNS TTL in the Surefire
configuration's {{<systemPropertyVariables>}}? That would propagate down to
the forked JVM processes that run the JUnit tests.
> mvn fs/s3 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
> Original Estimate: 0.5h
> Remaining Estimate: 0.5h

> 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.
