[jira] [Commented] (HADOOP-14125) s3guard tool tests aren't
isolated; can't run in parallel
[ https://issues.apache.org/jira/browse/HADOOP-14125?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15885842#comment-15885842 ]
Steve Loughran commented on HADOOP-14125:
-----------------------------------------
Stack showing problems. I actually think the cause of this failure is the usual intermittent consistency issue with {{ITestS3AContractRootDir}}}, but it is highlighting that more stuff is hanging off root, when it shouldn't

> s3guard tool tests aren't isolated; can't run in parallel
> ---------------------------------------------------------
>
> Key: HADOOP-14125
> URL: https://issues.apache.org/jira/browse/HADOOP-14125
> Project: Hadoop Common
> Issue Type: Sub-task
> Components: fs/s3, test
> Affects Versions: HADOOP-13345
> Reporter: Steve Loughran
>
> The {{S3GuardToolTestBase}} don't parallelize and break other tests. This can surface if you do a full run with -Ds3guard and -Ddynamo.
> # many of the test paths they create are being requested with absolute paths, e.g {{"/test-diff"}}.
> # the base class doesn't set up a per-forked-JUnit-test runner path in the bucket
> # and there's no cleanup at the end of each test case; teardown() is empty.
> Ideally, the tests should be made child classes of {{AbstractS3ATestBase}}, with its post-run cleanup, If that can't be done, then the tests must
> # use {{S3ATestUtils.createTestPath(super.getTestPath())} to create the base test path
> # clean up that dir in teardown if the FS instance is non-null. {{ContractTestUtils.cleanup()}} can do this.
> If it happens that the tests cannot run in parallel with others, then the build must be changed to exclude them from the parallel test run phase & include them in the serialized section.
