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*.
