Subject [jira] [Commented] (HADOOP-9421) Convert SASL to use ProtoBuf and add lengths for non-blocking processing
Date Thu, 20 Jun 2013 08:02:21 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-9421?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13688991#comment-13688991

Luke Lu commented on HADOOP-9421:
---------------------------------

bq. As described, optimize token path.

[Your patch|https://issues.apache.org/jira/secure/attachment/12588738/HADOOP-9421.patch] still
doesn't have the proper client initiation support:
# Only works with token auths that use digest-md5, will require major protocol change to optimize
for SCRAM (modern digest-md5 replacement) or Kerberos and anything SASL mechanisms that hasInitialResponse.
# fallback prevention seems broken as the patch didn't modify TestSaslRpc#testSimpleServerWith*Token
and still pass these tests.
