Review comment:
I don't think that's a good setup assumption. This tool is a developer tool,
intended for testing Fluo (and Accumulo) by its contributors. It is not a tool
for public release, and is not intended as a cluster provisioning tool for
production environments. HA is not necessarily worthwhile for the use case
Muchos was written for.
