Phil Yang updated HBASE-16266:
------------------------------
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 (was: 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 ScannerTimeoutException, we can just reset the scanner like
NotServingRegionException)
