> 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.
