Vinod Kumar Vavilapalli commented on MAPREDUCE-2908:
----------------------------------------------------
bq. What was the motivation behind renaming Queue to AbstractQueue in the
capacity scheduler?
Yeah, that was the only big change, I should've commented about it before
itself. This was to address a findBugs warning which complained that
_o.a.h.yarn.server.resourcemanager.scheduler.capacity.Queue_ implements the top
level _o.a.h.yarn.server.resourcemanager.scheduler.Queue_ and shares the same
name but different packages. I myself did find it to be confusing, so renamed
it instead of excluding it from the warning list.
