Description

When VictimHandler is used we use the bucket cache to cache those blocks that are evicted. So in case of where we close the hfile and call evictBlocksByHfileName - I think it still makes sense to call evict on the vicitmHandler also. Else the victimHandler is going to just occupy the space till the eviction thread in that vicitm handler clears it.
