[jira] [Created] (HADOOP-10129) Distcp may succeed when it fails

Daryn Sharp created HADOOP-10129:
------------------------------------

             Summary: Distcp may succeed when it fails
                 Key: HADOOP-10129
                 URL: https://issues.apache.org/jira/browse/HADOOP-10129
             Project: Hadoop Common
          Issue Type: Bug
          Components: tools/distcp
    Affects Versions: 2.0.0-alpha, 0.23.0, 3.0.0
            Reporter: Daryn Sharp
            Assignee: Daryn Sharp
            Priority: Critical


Distcp uses {{IOUtils.cleanup}} to close its output streams w/o previously attempting to close the streams.  {{IOUtils.cleanup}} will swallow close or implicit flush on close exceptions.  As a result, distcp may silently skip files when a partial file listing is generated, and/or appear to succeed when individual copies fail.
