Subject [jira] [Commented] (HDFS-9123) Copying from the root to a subdirectory should be forbidden
Date Wed, 23 Sep 2015 19:04:04 GMT

    [ https://issues.apache.org/jira/browse/HDFS-9123?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14905045#comment-14905045

Wei-Chiu Chuang commented on HDFS-9123:

Agree with Yongjun's comment #2. The shell currently is not designed to throw internal exceptions.
 It would require another lira to make a better test design though.

> HDFS forbids copying from a directory to its subdirectory (e.g. hdfs dfs -cp /abc /abc/xyz)
as otherwise it could cause infinite copying (/abc/xyz/xyz, /abc/xyz/xyz, /abc/xyz/xyz/xyz,...
> However, the existing path validation fails if the source path is the root, causing infinite
copying, until the disk space is filled up.
