    Description

      Persist list of Hfiles names for which prefetch is completed when persist for in-memory bucket cache mapping state is enabled.

      We need to persist the Set, which contains a list of all the HFiles for which the prefetch has completed along with the In-memory state of the bucket cache so that when we restart and if any prefetch is scheduled again for the same HFile and we already have the in-memory state retrieved, we can skip the prefetch for it.
