Subject [jira] [Commented] (HADOOP-9421) Convert SASL to use ProtoBuf and add lengths for non-blocking processing
Date Fri, 07 Jun 2013 18:38:22 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-9421?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13678288#comment-13678288

Luke Lu commented on HADOOP-9421:

bq. The IpSerializationType change is orthogonal to this patch, so I'd like to defer to another
jira if that's ok?

Yes. HADOOP-9630

bq. I changed the authMethod in the connection header to specify the authentication protocol
- in this case none, or sasl, to allow for future protocols. I think that's what you wanted?

I wanted to get rid of the byte completely and let client always do a SASL call with RpcSaslProto
with an initial auth method field, so that the client initiation is extendable. If you really
want to use the byte for auth protocol NONE vs SASL (and potential other protocols), I'm fine
(but change AuthCallId in the javadoc to AuthProtocol to be consistent). The main thing I'd
like to have is be able to evolve client initiation (to save a round-trip with cached mechs)
without having to change the RPC version again.
