> Key: HADOOP-16186
> URL: https://issues.apache.org/jira/browse/HADOOP-16186
> Project: Hadoop Common
> Issue Type: Sub-task
> Components: fs/s3
> Affects Versions: 3.3.0
> Reporter: Steve Loughran
> Assignee: Gabor Bota
> Priority: Major
>
> Test run options. NPE in test teardown
> {code}
> -Dparallel-tests -DtestsThreadCount=6 -Ds3guard -Ddynamodb
> {code}
> If you look at the code, its *exactly* the place fixed in HADOOP-15827, a change which HADOOP-15947 reverted.
> There's clearly some codepath which can surface which is causing failures in some situations, and having multiple patches switching between the && and || operators isn't going to to fix it
