Benoy Antony commented on HADOOP-9421:
--------------------------------------
An alternative approach in choosing a mechanism is to model after the SSL
protocol.
Here Client does "ClientHello" to server with a list of mechanisms it supports.
The server maintains a prioritized list of mechanisms it supports. The server
picks the strongest mechanism from ClientHello and does ServerHello to client
to inform the chosen mechanism.
The client can pass "mechanism neutral" hints/information as part of
clientHello.
The server can pass mechanism specific information (eg. principal, realm etc)
as part of ServerHello.
