Subject [jira] Commented: (HADOOP-6419) Change RPC layer to support SASL/token based mutual authentication
Date Wed, 20 Jan 2010 20:32:54 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-6419?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12802976#action_12802976

Kan Zhang commented on HADOOP-6419:
-----------------------------------

Attached a new patch that takes into account Doug' suggestion. On the client side, all SASL
logic is encapsulated in SaslRpcClient which implements SaslClient. However, similar things
are harder to do for the server side since we use non-blocking IO.

> 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.
