Anne Yu commented on SENTRY-1471: --------------------------------- [~vspec...@gmail.com], thanks for pointing out this issue. Since you've spent quite some time investigating the issue, do you have idea of after fix SENTRY-1471, why TestHDFSIntegrationAdvanced starts to fail? I guess this jira is meant to fix catch logic in verifyOnAllSubDirsHelper and verifyQuery APIs, but without fixing the test failures, this patch won't pass upstream-qa. Or do you have a jira filed already for real TestHDFSIntegrationAdvanced test failures? In that case, I can wait for it to be fixed. > TestHDFSIntegrationBase.java implements HDFS ACL checking and query > verification incorrectly > -------------------------------------------------------------------------------------------- > > Key: SENTRY-1471 > URL: https://issues.apache.org/jira/browse/SENTRY-1471 > Project: Sentry > Issue Type: Bug > Components: Sentry > Reporter: Vadim Spector > Assignee: Anne Yu > > verifyOnAllSubDirsHelper() in TestHDFSIntegrationBase.java has a bug. When > the number of failed 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. It will > not only fix the problem, but also make debugging easier. Current code > "Assert.assertTrue(isSucceeded);" throws away valuable information about the > expected vs detected number of database rows. > Note: the above problems were introduced by SENTRY-1454. Suggested fixes > match the original code prior to SENTRY-1454. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
