Andrew Purtell commented on HBASE-14624:
----------------------------------------
bq. Seems we can not avoid an extra object creation (Iterator) with every call !
Noticed this also. Use an alternative to Set where you can pull elements from the head or
tail without allocating a throwaway iterator just to effectively do the same. Maybe one of
the implementations of Deque?
> BucketCache.freeBlock is too expensive
