Raghu Angadi commented on HADOOP-6419:
--------------------------------------
I think so. RPC implementation in Hadoop is well isolated from user code,
making it some what easier to replace with it with another one. I am interested
in implementing a Netty based RPC server (as prototype).. I am planning to
spend more time on this this week. will check how it would fit in with AVRO-341
and HDFS-892.

> The authentication mechanism to use will be SASL DIGEST-MD5 (see RFC-2222 and
> RFC-2831). Since J2SE 5, Sun provides a SASL implementation by default. Both
> our delegation token and job token can be used as credentials for SASL
> DIGEST-MD5 authentication.
