As discussed here and here at
MAPREDUCE-1604, the job-acls feature is currently unstable. Without MAPREDUCE-1664, job-acls are practically useless because of their problematic interactions with queue-acls. Removing them for 0.21 will both relieve ourselves of these problems as well as the burden to support the backwards compatibility of the configuration options as well as the going-to-be-changed semantics of the feature. This jira is about removing the documentation from 0.21 so that the completed feature can be added in 0.22 with ease.
