Subject [jira] [Commented] (HBASE-6788) Convert AuthenticationProtocol to protocol buffer service
Date Fri, 14 Dec 2012 06:52:16 GMT

    [ https://issues.apache.org/jira/browse/HBASE-6788?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13532100#comment-13532100

Gary Helmling commented on HBASE-6788:

[~saint.ack@gmail.com] Thanks for the review.  Sorry to update it again just after you've
taken a look.

bq. This AuthenticationTokenIdentifier implements the Hadoop TokenIdentifier. 

Yes, AuthenticationTokenIdentifier still needs to retain the Writable interface since Token
(Hadoop class) uses this internally, and we rely on Token to tie in transparently to the Hadoop
UGI credentials.

bq. public static final long VERSION = 0L;

Nice catch, no longer needed.

bq. + return AuthenticationProtos.AuthenticationService.newReflectiveService(this);

Since TokenProvider implements AuthenticationService.Interface, this translates that back
into a Service instance.

> With coprocessor endpoints now exposed as protobuf defined services, we should convert
over all of our built-in endpoints to PB services.
> AccessControllerProtocol was converted as part of HBASE-5448, but the authentication
token provider still needs to be changed.
