>
> The reference counting on the blocks does not work correctly when the
> HalfStorefileReader is used for compaction/scans.
> The reason is that getFirstKey and getLastKey API create a new scanner but
> does not do the needed close() call and because of that we do not decrement
> the count on the blocks. The same impact will also be observed on the ref
> count that we maintain on the reader. Issue found when I was trying to test
> some other feature with lot of evictions.
