The Hadoop security project called Ranger supposedly was named in tribute to Chuck Norris in his "Walker, Texas Ranger" role. The project has its roots in XA Secure, which was acquired by Hortonworks, then renamed to Argus before settling in at the Apache Software Foundation as Ranger.
When Hadoop started, it was a set of loosely coupled parts primarily used in the back end of the big Internet companies like Yahoo. These parts were wrapped into distributions and marketed as Hadoop by the likes of MapR, Cloudera, and Hortonworks.
