----------------------------------------
I got this error when running in parallel mode (though root directory test was
in sequential).

I'm not sure if this has been reported?
> explicitly exclude s3a root dir ITests from parallel runs

> Key: HADOOP-14321
> URL: https://issues.apache.org/jira/browse/HADOOP-14321
> Project: Hadoop Common
> Issue Type: Sub-task
> Components: fs/s3, test
> Affects Versions: 2.8.0
> Reporter: Steve Loughran
> Assignee: Steve Loughran
> Priority: Minor
> Attachments: HADOOP-14321-branch-2-001.patch
>
>
> the s3 root dir tests are running, even though they are meant to be excluded
> via the statement
> {code}
> <exclude>**/ITest*Root*.java</exclude>
> {code}
> Maybe the double * in the pattern is causing confusion. Fix: explicitly list
> the relevant tests (s3, s3n, s3a instead)
