Decouple the HBase internals such that someone can implement their own SASL-based authentication mechanism and plug it into HBase RegionServers/Masters. Comes with a design doc in dev-support/design-docs and an example in hbase-examples known as "Shade" which uses a flat-password file for authenticating users.

This directory hosts design docs and proposals. Add here final or near-final writeups so they are easy to find and part of the code base. Be warned that final delivery may not be a perfect reflection of what is captured at design time; implementation bends as it encounters hurdles not conceptualized at design-time. The effort at capturing all design in a single directory ratherthan spread about JIRA as attachments was begun in September of 2017.
