> 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}}.
