Subject [jira] [Commented] (MAPREDUCE-5275) Mapreduce API: TokenCache incompatibility issues with MR1
Date Mon, 03 Jun 2013 20:00:20 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-5275?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13673491#comment-13673491

Vinod Kumar Vavilapalli commented on MAPREDUCE-5275:

bq. Yes, in 1.x it has the public keyword, but it's annotated @InterfaceAudience.Private and
the class is annotated @InterfaceStability.Evolving. A method assuming a 1-to-1 fs to token
mapping cannot work with viewfs and 1-to-many.
I didn't mean java public. I don't see the annotation in branch-1. It is commented in code
- that doesn't mean it is private. Which branch are you seeing?

bq. The real question is why are we re-adding evolving/private methods removed 9 months ago?
We are just comparing 1.x with 2.x and fixing all changes *if possible*.
