Description

Currently, we maintain a list of Hfiles on disk for which prefetch is complete and avoid prefetching those files after a restart. But we don't handle cases where blocks are evicted from the cache. This ticket is for updating the list of prefetched files when the region is moved but the blocks from that region are not evicted.
