Subject [jira] Created: (HBASE-2104) No exception thrown while during scanning no connection can be made to the regionserver

No exception thrown while during scanning no connection can be made to the regionserver
---------------------------------------------------------------------------------------

                 Key: HBASE-2104
                 URL: https://issues.apache.org/jira/browse/HBASE-2104
             Project: Hadoop HBase
          Issue Type: Bug
          Components: client
    Affects Versions: 0.20.1
            Reporter: Robert Hofstra


When a regionservers is stopped (shutdown or crash) and on the same moment a client performs
a scan on that regionserver no exception is thrown at client side nor a reconnect toanother
regionsserver is tried.
The ResultScanner.Iterator.hasNext ()just returns false, so the client assumes that there
are no records anymore.


In the ScannerCallable.call I notice that the java.net.ConnectionException is catched and
a empyt Result array is returned.
