> FlinkTopologyBuilder cannot handle multiple input streams
> ---------------------------------------------------------

> Key: FLINK-2837
> URL: https://issues.apache.org/jira/browse/FLINK-2837
> Project: Flink
> Issue Type: Bug
> Components: Storm Compatibility
> Reporter: Matthias J. Sax
> Assignee: Maximilian Michels
>
> FlinkTopologyBuilder cannot handle multiple input streams correctly. Instead
> of union the incoming streams, it replicates the consuming bolt and each
> (logical) instance processes one of the input streams.
> For example:
> {noformat}
> final FlinkTopologyBuilder builder = new FlinkTopologyBuilder();
> builder.setSpout(spoutId1, new FiniteRandomSpout(0, 10));
> builder.setSpout(spoutId2, new FiniteRandomSpout(1, 8));
> builder.setSpout(spoutId3, new FiniteRandomSpout(2, 13));
> builder.setBolt(boltId, new MergerBolt())
> .shuffleGrouping(spoutId1)
> .shuffleGrouping(spoutId2)
> .shuffleGrouping(spoutId3);
> builder.setBolt("sink", new BoltPrintSink(new SimpleOutputFormatter()))
> .shuffleGrouping(boltId);
> {noformat}
> will only print the data from a single source instead of all sources.
