Community is improving Hadoop RPC and SASL authentication

Very interesting, Hadoop active guy Darn Sharp is working on improving RPC and SASL to support his list:

  • support multiple SASL mechanisms
  • support negotiation of SASL mechanisms
  • support multiple protocols per mechanism
  • add server id hints for sasl clients
    • support kerberos auth to servers with arbitrary service principals
    • completely decouple host/ip from tokens
  • aforementioned supports servers with multiple NICs
  • clients may access a server via any hostname, ip, or even CNAME for a server

Would watch this for our support to implement the token based authentication.
