]

Phil Yang updated HBASE-16266:
------------------------------
    Attachment: HBASE-16266-v3.patch

HBASE-2481 asserts we should get timeout exception when ScannerUnknowException, so we can
remove TestScannerTimeout.test2481 now

> 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
