Luke Lu commented on HADOOP-9421: --------------------------------- I do recognize what server id can enable: distinct services on the same ip:port, a la the HTTP host header and SSL server name indication. It's an "insane" solution for HA because HA will not be seamless due the race condition I mentioned. It's fixable with more negotiate rounds with more logic though :) > Convert SASL to use ProtoBuf and provide negotiation capabilities > ----------------------------------------------------------------- > > Key: HADOOP-9421 > URL: https://issues.apache.org/jira/browse/HADOOP-9421 > Project: Hadoop Common > Issue Type: Sub-task > Affects Versions: 2.0.3-alpha > Reporter: Sanjay Radia > Assignee: Daryn Sharp > Priority: Blocker > Fix For: 3.0.0, 2.1.0-beta, 2.2.0 > > Attachments: HADOOP-9421.patch, HADOOP-9421.patch, HADOOP-9421.patch, > HADOOP-9421.patch, HADOOP-9421.patch, HADOOP-9421.patch, HADOOP-9421.patch, > HADOOP-9421.patch, HADOOP-9421.patch, HADOOP-9421-v2-demo.patch > > -- This message is automatically generated by JIRA.
