@InterfaceAudience.Private
public class CellTypeEncoder
extends Object

Detect if every KV has the same KeyValue.Type, in which case we don't need to store it for each KV. If(allSameType) during conversion to byte[], then we can store the "onlyType" in blockMeta, therefore not repeating it for each cell and saving 1 byte per cell.
