Two test failures. Could they be related? If not, is there some (test?) change in trunk to cherrypick?
```
Test Result (2 failures )
org.apache.hadoop.hdfs.TestDFSClientRetries.testLeaseRenewAndDFSOutputStreamDeadLock
org.apache.hadoop.hdfs.TestDFSClientRetries.testLeaseRenewSocketTimeout
```

I re-ran the jenkins build and now a different test has failed, so I really don't think this PR is the problem

@steveloughran I don't think the test failures are related to the changes in this PR. I think that TestDFSClientRetries is flaky because the DFSClientFaultInjector is not reset after each test method. I'm not sure why this issue doesn't present in trunk, maybe the junit 4/5 difference could affect that. I don't see anything targeted to cherry-pick to fix this.
