Steve Vaughan commented on HADOOP-18419:
----------------------------------------
The documentation for Surefire states that this has defaulted to true since
version 2.12. I was surprised to see the use of "-Dtest=NoUnitTests" in the
Hadoop build since I would have expected that to fail. I actually started
looking into the Surefire code thinking it must be a special case I didn't
know. I can't explain why 3.0.0-M1 wouldn't have complained.
If we want to maintain the ability to filter on non-existent tests, then
overriding surefire.failIfNoSpecifiedTests to make it false is the correct
approach
> Don't fail when using -DNoUnitTests

> Project: Hadoop Common
> Issue Type: Bug
> Components: build
> Affects Versions: 3.4.0
> Reporter: Steve Vaughan
> Assignee: Steve Vaughan
> Priority: Critical
> Labels: pull-request-available
>
> There are commands in hadoop.sh that use -Dtest=NoUnitTests. I believe this
> is intended to replace -DskipTest, by not matching any tests. This causes an
> issue since the default for surefire.failIfNoSpecifiedTests is true.
> Updating those commands to override the default will address the issue.
