Andor Molnar commented on HBASE-26666:
--------------------------------------
I suggest to implement Netty-based TLS encryption for this in Master and RS.
Most of the implementation can be copied from the ZooKeeper project where it
was implemented recently.
> Address bearer token being sent over wire before RPC encryption is enabled

> Key: HBASE-26666
> URL: https://issues.apache.org/jira/browse/HBASE-26666
> Project: HBase
> Issue Type: Sub-task
> Reporter: Josh Elser
> Priority: Major
> Fix For: HBASE-26553
>
>
> Today, HBase must complete the SASL handshake (saslClient.complete()) prior
> to turning on any RPC encryption (hbase.rpc.protection=privacy,
> sasl.QOP=auth-conf).
> This is a problem because we have to transmit the bearer token to the server
> before we can complete the sasl handshake. This would mean that we would
> insecurely transmit the bearer token (which is equivalent to any other
> password) which is a bad smell.
> Ideally, if we can solve this problem for the oauth bearer mechanism, we
> could also apply it to our delegation token interface for digest-md5 (which,
> I believe, suffers the same problem).
