> In KeyValueDecoder & ByteBuffKeyValueDecoder,  we pass a byte buffer to 
> initialize the Cell without a sanity check (check each field's offset&len 
> exceed the byte buffer or not), so ArrayIndexOutOfBoundsException may happen 
> when read the cell's fields, such as HBASE-21379,  it's hard to debug this 
> kind of bug. 
> An earlier check will help to find such kind of bugs.
