Looks like you are anchoring the tuple here but there is no ack in WordCountTopologyNode.WordCount Bolt. This might be the one causing the fail count go up and also completeLatency.  I removed the anchorTupleId and in storm.js anchors as part of the message. There is no failed tuples and lower completeLatency of 41.
