Daryn Sharp commented on HADOOP-8131:
-------------------------------------
When using a 1-arg put, the shell default to using the pwd. If the target
doesn't exist, the shell assumes it's a rename of the src file. So the temp
file "$p._COPYING_" becomes ".._COPYING_". The move at the end of the copy
tries to rename the temp file to ".", which is interpreted as the pwd, so the
rename is a no-op.
> FsShell put doesn't correctly handle a non-existent dir
