stack commented on HBASE-2104:
------------------------------
@Robert Is part of the issue the fact that Iterator is being used? Its hasNext
and next methods do not throw Exceptions? If you used the next methods that do
throw exceptions, would that work? Or rather, ScannerCallable should let out
certain types of exceptions? Any chance of a patch? One that works for you?
That'd help us out. Thanks.

> 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.
