> In fast_hdfs_resource, setMode is used to set the permissions on the Resource object using the specified mode. Passing in the mode as a string for FsPermission is what results in the problem because the constructor that is used with string as argument uses the UmaskParser. Umask values are slightly different from standard modes as they cannot specify t (sticky bit) or X.
> Passing in the argument as a short is probably what is needed here to enable using the FsPermission code that accounts for the sticky bit.
