> In RSRpcServices.scan, we will set a time limit equaling to
> Math.min(scannerLeaseTimeoutPeriod, rpcTimeout) / 2, and will response
> heartbeat message if we reach this limit. However, two timeout settings
> (hbase.client.scanner.timeout.period and hbase.rpc.timeout) are read from
> RS's configure, which may be different from client's. If client's setting is
> much less than server's, there may still be timeout at client side.
