Summary: Sanity check in BaseDecoder#parseCell
Key: HBASE-21401
URL: https://issues.apache.org/jira/browse/HBASE-21401
Project: HBase
Issue Type: Sub-task
Reporter: Zheng Hu
Assignee: Zheng Hu


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-213, it's hard to debug this kind of bug.

An earlier check will help to find such kind of bugs.

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.
