> 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.
