----------------------------------------
Please use us...@apex.apache.org mailing list for asking questions about apex
before opening an JIRA. Use JIRA for bug/improvement related to code and
documentation.
The stream for which exception is thrown is MapData, and the stream is not
present in the code snipped you have provided. In general you can't use the
same port twice if using addStream api. For sending data to multiple operators
you can connected same output port to multiple input ports.
dag.addStreams("streamname", outputPorts, in1, in2, in3 ...)
You can not connect single input port to multiple output ports.
