    Description

      HDFS-12130 optimizes permission check, and invokes permission checker recursively for each component of the tree, which works well for FSPermission checker.

      But for certain external authorizers it may be more efficient to make one call with subaccess, because often they don't have to evaluate for each and every component of the path.
