Subject [jira] [Commented] (HADOOP-9421) Convert SASL to use ProtoBuf and add lengths for non-blocking processing
Date Wed, 19 Jun 2013 06:04:22 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-9421?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13687645#comment-13687645

Sanjay Radia commented on HADOOP-9421:
--------------------------------------

bq. Client today does send/(send/read)+, and now it's send/read/(send/read)+.
Daryn, I assume the first read in the new version is to read the server's list of auth methods.
Generally the preferred approach is: client sends preferred auth with a list of alternatives
client can do and server either accepts it or throws back a counter with one of the alternates
that the client proposed. This would avoid an extra trip in the normal case.
