> As discussed in HADOOP-11321, the local file system implements file and directory creation
as a two-step process: create followed by chmod to set the caller's requested permissions.
 This causes a brief window in which the new file or directory may have wider permissions
than what the caller requested.  HADOOP-11321 fixed this specifically for Windows as a side
effect of fixing a bug in writing to an SMB share.  This issue tracks fixing it specifically
for Linux.
