Vinod Kumar Vavilapalli commented on MAPREDUCE-5130:
----------------------------------------------------
bq. Filed MAPREDUCE-5236
MAPREDUCE-5236 seemed incorrect when looked in isolation. Commented there. Can
you just modify that to mean that the test-case is failing? This is another
general suggestion: File tickets describing the problem and then propose the
solution as a comment.
bq. computeNumSlotsPer* isn't used anywhere in the code. As there are no more
slots in YARN, and it is not a public API, would it not make the most sense to
remove it?
+1, let's remove the method itself here.
