RE: storm-kafka integration duplication of messages

[Max Evers]

The AllGrouping was intended to duplicate the messages to HDFS and the
outbound kafka, what were are seeing is the duplicaiton of messages from
the kafkaspout, so the same message is seen multiple times in hdfs AND in
the outbound kafka, as well as the logs of the intermediate bolt handling
the deserialization.  Presently there is not much more going on in storm
that the deserialization.  I wanted to get the skeleton of the flow working
before I  introduced new complications inside of storm.
