Subject Re: what's different between numberOfStores and numberOfStorefiles in region status variables

Each column family is a "store" (in fact there is one store per region and column families).
Each region may have more than one actual HFile per store.
A new HFile (storefile) is create for example when the memstore is flushed to disk. When too
many HFiles have accumulated for a store, they are compacted to fewer, larger files.
