> verifyOnAllSubDirsHelper() in TestHDFSIntegrationBase.java has a bug. When the number of retries exceeds max value (the "else" portion of "if (retry > 0)" statement, it erroneously assigns hasSucceeded = true. It means that verifyOnAllSubDirsHelper() never returns false.
> Once the problem was fixed in a local development branch, several tests in TestHDFSIntegrationAdvanced.java started failing. TestHDFSIntegrationEnd2End tests are still ok.
> Also, it is unfortunate that TestHDFSIntegrationBase() returns boolean instead of throwing the original AssertionError which contains information about expected vs. found ACL permissions - this information is invaluable for debugging. The fix is easy - the to-be-fixed "else" portion is inside the "catch (Throwable th)" clause, so it should just re-throw caught exception. This makes "hasSucceeded" variable unnecessary - verifyOnAllSubDirsHelper() should have "void" return type.
> The same problem exists in verifyQuery(), also  in TestHDFSIntegrationBase.java. The "else" clause of "if (retry > 0)" also assigns "isSucceeded = true;" leading to the same problem - it never fails. Suggested solution would be the same - just re-throw the exception.
