Subject [jira] [Commented] (HADOOP-9382) Add dfs mv overwrite option
Date Tue, 04 Aug 2015 18:56:05 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-9382?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14654154#comment-14654154
] 

Colin Patrick McCabe commented on HADOOP-9382:
----------------------------------------------

What is the behavior supposed to be when the source is a directory, and the destination is
a file?  In UNIX, a directory cannot be overwritten by a file.

{code}
cmccabe@keter:~> mkdir d
cmccabe@keter:~> touch f
cmccabe@keter:~> mv d f
mv: overwrite ‘f’? y
mv: cannot overwrite non-directory ‘f’ with directory ‘d’
cmccabe@keter:~> mv -f c b
mv: cannot overwrite non-directory ‘f’ with directory ‘d’
{code}
