Zheng Hu commented on HBASE-22005:
----------------------------------

The keyvalue looks like the following : 
{code}
,\x00\x00\x18   \x00\x00\x00\x0C  \x00\x09 $$$$$$$31   \x02          cf   q     
\x00\x00\x01i\xBF\x1E\xF4,   \x04     
\x00\x00\x01i\xBF\x1E\xF3\xE5\x00\x00\x01\xCE
   keyLen           valueLen       rowLen   rowkey     FamilyLen     CF   CQ    
 timestamp                   type         12-values
{code}

the first byte is exactly 44 , which means length of the cell.  so there's one 
bye mis-encoding when enable the hbase.ipc.server.reservoir.enabled

> Use ByteBuff's refcnt to track the life cycle of data block
