             Summary: Speed up S3A test runs
                 Key: HADOOP-16415
                 URL: https://issues.apache.org/jira/browse/HADOOP-16415
             Project: Hadoop Common
          Issue Type: Sub-task
          Components: fs/s3
    Affects Versions: 3.3.0
            Reporter: Steve Loughran


S3A Test runs are way too slow.

Speed them by

* reducing test setup/teardown costs
* eliminating obsolete test cases
* merge small tests into larger ones.

One thing i see is that the main S3A test cases create and destroy new FS 
instances; There's both a setup and teardown cost there, but it does guarantee 
better isolation.

Maybe if we know all test cases in a specific suite need the same options, we 
can manage that better; demand create the FS but only delete it in an 
@Afterclass method. That'd give us the OO-inheritance based setup of tests, but 
mean only one instance is done per suite
