> In Hadoop 2, it is impossible to use {{copyToLocal}} to copy a file from HDFS
> to a destination on an SMB share. This is because in Hadoop 2, the
> {{copyToLocal}} maps to 2 underlying {{RawLocalFileSystem}} operations:
> {{create}} and {{setPermission}}. On an SMB share, the user may be
> authorized for the {{create}} but denied for the {{setPermission}}. Windows
> denies the {{WRITE_DAC}} right required by {{setPermission}} unless the user
> has Full Control permissions. Granting Full Control isn't feasible for most
> deployments, because it's insecure. This is a regression from Hadoop 1,
> where {{copyToLocal}} only did a {{create}} and didn't do a separate
> {{setPermission}}.
