> Datanode#checkSecureConfig currently check the following to determine if
> secure datanode is enabled.
> # The server has bound to privileged ports for RPC and HTTP via
> SecureDataNodeStarter.
> # The configuration enables SASL on DataTransferProtocol and HTTPS (no plain
> HTTP) for the HTTP server.
> Authentication of Datanode RPC server can be done either via SASL handshake
> or JSVC/privilege RPC port.
> This guarantees authentication of the datanode RPC server before a client
> transmits a secret, such as a block access token.
> Authentication of the HTTP server can also be done either via HTTPS/SSL or
> JSVC/privilege HTTP port. This guarantees authentication of datandoe HTTP
> server before a client transmits a secret, such as a delegation token.
> This ticket is open to allow privileged HTTP as an alternative to HTTPS to
> work with SASL based RPC protection.

> cc: [~cnauroth] , [~daryn], [~jnpandey] for additional feedback.
