Steve Loughran updated HADOOP-19210:
------------------------------------
    Description: 
Not noticed this before, but the unit tests TestS3AAWSCredentialsProvider and 
TestS3AInputStreamRetry are so slow they will be hurting over all test 
performance times: no integration tests will start until these are all complete.


{code}

mvn test -T 1C -Dparallel-tests

...
[INFO] Tests run: 5, Failures: 0, Errors: 0, Skipped: 0, Time elapsed: 37.877 s 
- in org.apache.hadoop.fs.s3a.TestS3AInputStreamRetry
...
[INFO] Tests run: 25, Failures: 0, Errors: 0, Skipped: 0, Time elapsed: 90.038 
s - in org.apache.hadoop.fs.s3a.TestS3AAWSCredentialsProvider
{code}

The PR cuts total execution time of a 10 thread test run from 3 minutes to 2:30
