> Inconsistent enforcement of umask between FileSystem and FileContext

>
> The {{FileSystem}} and {{FileContext}} APIs are inconsistent in enforcement 
> of umask for newly created directories.  {{FileContext}} utilizes 
> configuration property {{fs.permissions.umask-mode}} and runs a separate 
> {{chmod}} call to guarantee bypassing the process umask.  This is the 
> expected behavior for Hadoop as discussed in the documentation of 
> {{fs.permissions.umask-mode}}.  For the equivalent {{FileSystem}} APIs, it 
> does not use {{fs.permissions.umask-mode}}.  Instead, the permissions end up 
> getting controlled by the process umask.
