> --------------------------------------------------------------
>
> Key: ACCUMULO-3855
> URL: https://issues.apache.org/jira/browse/ACCUMULO-3855
> Project: Accumulo
> Issue Type: Bug
> Components: proxy
> Reporter: Josh Elser
> Priority: Critical
> Fix For: 1.5.3, 1.6.3, 1.8.0, 1.7.1
>
>
> Inspecting ProxyServer, saw the following:
> {code}
> @Override
> public void update(String writer, Map<ByteBuffer,List<ColumnUpdate>> cells) throws TException {
> try {
> BatchWriterPlusException bwpe = getWriter(writer);
> addCellsToWriter(cells, bwpe);
> } catch (UnknownWriter e) {
> // just drop it, this is a oneway thrift call and throwing a TException seems to make all subsequent thrift calls fail
> }
> }
> {code}
> This means that calls to update which fail to get a BatchWriter (for whatever reason) will silently fail and appear to the user to have written data successfully. This is horrible.
> I'm not sure what the comment means either. I'm not sure why throwing a TException from the server would invalidate the connection, but perhaps I'm just ignorant of some finer details.
