------------------------------------
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.
