Looks like TestDFSClientRetries is timing out on tet runs, possibly related to JUnit 5 (though the class doesn't actually add an @Timeout declaration)
Does anyone want to look at this? Ideally by starting with a cleanup/modernise of the code -move from System.out to logging statements -try with resources on data blocks read/write -extend AbstractHadoopTestBase -add a long timeout like 5 minutes -use AssertJ for asserts -and intercept() for operations which want to intercept I promise I'll review it!
