-----------------------------------------------------------------
I wondered if maybe it was a difference in the parent class,
FileSystemContractBaseTest. Diffing the 2 versions, there's a few additional
tests and minor tweaks, the tests are annotated with @Test in Hadoop 3 but not
in Hadoop 2 (shouldn't be a factor here, as I'm also annotating my versions of
the failing tests with that), and there's a Timeout rule and an
ExpectedException.none rule. Neither strikes me as an obvious factor here...
edit: I actually added identical rules to that test and ran it with -Phadoop2,
and had the same issue. So I don't see any differences in the parent class from
Hadoop 2 to Hadoop 3 that are even remotely suspicous.

> HBOSS: Add Hadoop 2 / 3 profiles

> Key: HBASE-22437
> URL: https://issues.apache.org/jira/browse/HBASE-22437
> Project: HBase
> Issue Type: Improvement
> Components: hboss
> Reporter: Sean Mackrory
> Assignee: Sean Mackrory
> Priority: Major
> Labels: HBOSS
> Attachments: 0001-HBASE-22437-HBOSS-Add-Hadoop-2-3-profiles.patch
>
>
> Original discussion on HBASE-22149 indicated interest running HBOSS on Hadoop
> 2, and HBase itself maintains profiles for Hadoop 2 and 3. There's no
> fundamental reason we can't - there are some minor incompatibilities in the
> code, but no fundamental mismatch.
