> Follow-on from HBASE-20605:
> HBase 1.x has a check which ignores a directory permission check if you're using a specific filesystem which we think doesnt' do security properly.
> HBase 2.x dropped this check.
> Since the security of bulk-loaded data is dependent upon this directory permission (and thus the capabilities of the FileSystem), it would be better to have a consistent warning across branches.
> [~busbey] suggested that we make a WARN message which points admins to our Book (and write such a section if we don't have something sufficient already) and our supported filesystems, coupled with an option to disable that warning message.
