Andrew Kyle Purtell commented on HBASE-26708:
---------------------------------------------
[~bbeaudreault] I was/am confused by that because HBASE-26666 is a child of
HBASE-26553 which describes itself as "OAuth Bearer authentication mech plugin
for SASL". Can you or someone clean this up so we can clearly see what is going
on? Is it really a full TLS RPC stack? Because it looks to me like some TLS
fiddling to get a token that then sets up the usual wrapped SASL connection. It
is not native TLS support in the sense I mean and the sense that is really
required, which is TLS and only TLS end to end, possibly why it has not gotten
enough attention.
