Zheng Hu commented on HBASE-21401:
----------------------------------
I used the following cmd to make a benchmark:
nohup ./bin/hbase pe --rows=10000 --nomapred sequentialWrite 100 > perf.log
2>&1
|| Test Case || TotalMinTime|| TotalMaxTime || TotalAvgTime || AvgLantecy
||AvgTPS/QPS ||
|Before Patch #1| 8977ms| 10589ms| 9807ms| 953us|102167|
|Before Patch #2| 7971ms| 12184ms| 10965ms| 972us|92200|
|After Patch#1| 9080ms | 11133ms|10236ms | 984us| 97880|
|After Patch#2| 9031ms | 10667ms|9955ms | 970us| 100638|
we can see that, no much diff between BeforePatch and AfterPatch case.

> 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.
