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}
> Add dfs mv overwrite option
