Zheng Hu updated HBASE-21401:
-----------------------------
Release Note: Add a sanity check when constructing KeyValue from a byte[].
we use the constructor when we're reading kv from socket or HFIle or
WAL(replication). the santiy check isn't designed for discovering the bits
corruption in network transferring or disk IO. It is designed to detect bugs
inside HBase in advance. and HBASE-21459 indicated that there's extremely small
performance loss for diff kinds of keyvalue.

> 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.
