[jira] [Updated] (HBASE-16266) Do not throw ScannerTimeoutException when catch UnknownScannerException

     [ https://issues.apache.org/jira/browse/HBASE-16266?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

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)
