I may have missed it as it went by, but what was the evidence that the zk quorum actually
includes all the zookeeper nodes?  This could be answered by examination if the logs, but
more definitive and simpler might be to configure to use only one zk node instead of three.


The rationale here is that if difference drillbits talked to different zk modes they could
well have not known about each other.
