[jira] [Resolved] (ACCUMULO-3855) ProxyServer.update fails silently
if batchwriter doesn't exist
[ https://issues.apache.org/jira/browse/ACCUMULO-3855?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Christopher Tubbs resolved ACCUMULO-3855.
-----------------------------------------
Resolution: Won't Fix
Fix Version/s: (was: 1.7.1)
(was: 1.8.0)
(was: 1.6.3)
(was: 1.5.3)
Since this isn't really possible to address with the current design, I'm going to go ahead and close this as "Won't Fix", after discussing briefly with [~elserj] in IRC. It's a known potential problem, but not much we can do about it at this point. If somebody has an idea, we can revisit it later.

> Key: ACCUMULO-3855
> URL: https://issues.apache.org/jira/browse/ACCUMULO-3855
> Project: Accumulo
> Issue Type: Bug
> Components: proxy
> Reporter: Josh Elser
> Priority: Critical
>
> 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.
