Andras Bokor commented on HADOOP-10375:
---------------------------------------

[~stevel@apache.org],

I think it was solved by HADOOP-9361.
{code:title=RawLocalFilesystem.java#mkdirsWithOptionalPermission}
if (p2f.exists() && !p2f.isDirectory()) {
      throw new FileNotFoundException("Destination exists" +
              " and is not a directory: " + p2f.getCanonicalPath());
}
{code}

Do you agree?

> if you mkdir() on a path where there is already a file, the operation does
> not fail. Instead the operation returns 0.
> This is at odds with the behaviour of HDFS. 
> HADOOP-6229 add the check for the parent dir not being a file, but something similar is needed for the destination dir itself
