Sean Busbey commented on HBASE-22197:
-------------------------------------

Anyone implementing these docs can probably use the old wiki as a guide, but you'll have to look at current code because I have not checked if it is accurate still.

> Got some questions today about delegation tokens. The asker referenced this very old page from the old HBase wiki (which we deprecated as defunct ages ago):
> https://wiki.apache.org/hadoop/Hbase/HBaseTokenAuthentication
> I was going to refer them to the up to date docs, since I thought we migrated all the content. However, a review of the current Ref Guide shows that we do not have docs on delegation tokens.
> Ideally this would be 2 sections:
> * an addition to the "secure configuration" section that explained how to use delegation tokens in a secure cluster, with the primary example of their use in MR and/or spark
> * an appendix that explains the current implementation for those working on hbase internals
