ITestS3AFileOperationCost#testFakeDirectoryDeletion failing after
OutputCommitter patch
Sean Mackrory created HADOOP-15079:
--------------------------------------
Summary: ITestS3AFileOperationCost#testFakeDirectoryDeletion failing after OutputCommitter patch
Key: HADOOP-15079
URL: https://issues.apache.org/jira/browse/HADOOP-15079
Project: Hadoop Common
Issue Type: Bug
Affects Versions: 3.1.0
Reporter: Sean Mackrory
Priority: Critical
I see this test failing with "object_delete_requests expected:<1> but was:<2>". I printed stack traces whenever this metric was incremented, and found the root cause to be that innerMkdirs is now causing two calls to delete fake directories when it previously caused only one. It is called once inside createFakeDirectory, and once directly inside innerMkdirs later:
