    Description

      Now in scanner we have heartbeat to prevent timeout. The time blocked on ResultScanner.next() may much longer than scanner timeout. So it is no need any more to throw ScannerTimeoutException when server throws UnknownScannerException, we can just reset the scanner like NotServingRegionException
