Description

The HDFS-4685 feature branch has introduced a helper method for getting an inode feature of a particular class: INodeWithAdditionalFields#getFeature. Currently, this is only called by code related to ACLs, but we can also use the same method to reduce code duplication in the various INodeDirectory methods that get different kinds of features.
