gaojinchao commented on HBASE-3848:
-----------------------------------

Sorry, I make a mistake for issue workflow. 

I downloaded the code for Trunk and verified it yesterday. It was ok.
but I find requests is requests/second in version 0.90.2, it is a sum  for hearbeat period
 in TRUNK .

I don't know your case.  but I will try to study the code for TRUNK.
