[jira] Issue Comment Edited: (HADOOP-5762) distcp does not copy empty directories

    [ https://issues.apache.org/jira/browse/HADOOP-5762?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12707152#action_12707152 ]

The problem happens if any of the source paths is an empty directory. It's because source directories are not "visited" in the inner loop that checks for files and directories to be copied and, thus, are not added to _distcp_src_files.

> If I have an empty directory /testdir1 and then I run the command bin/hadoop distcp /testdir1 /testdir2, the command completes successfully, but does not create the empty directory /testdir2.
