Subject [jira] [Commented] (HADOOP-13886) s3guard: ITestS3AFileOperationCost.testFakeDirectoryDeletion failure
Date Mon, 12 Dec 2016 13:42:58 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-13886?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15741922#comment-15741922

Steve Loughran commented on HADOOP-13886:
-----------------------------------------

my test, I believe. It's using the s3 metrics to count the #of fake directory operations,
that is: measure side effects happening internally.

I think we'll just need to have this test disabled when s3guard is in charge, as it's not
creating things any more
