Robert Hofstra commented on HBASE-2104:
---------------------------------------
In our case, we building a lucune search index with a hadoop from entries in
hbase
When a regionserver is stopped (because it's having problems) this index is
smaller, because not all entries are included.
What I expected, is a failed task in hadoop. Which result in a a new attempt to
process the task, which could succeed, when another regionserver is serving the
region.
> No exception thrown while during scanning no connection can be made to the
> regionserver

> 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.
