>
> Looking at the code related to the root tablet I think it currently chooses
> the first uri listed in instance.volumes and uses that to store root table
> files. If this config changes it seems like Accumulo will not see its root
> table files.
> Two possible ways of handling this are
>
> # Have init choose a uri from instance.volumes and store that in zookeeper,
> much like each tablet uri is chosen and stored in the metadata table.
> # user all namenodes listed in instance.volumes to store root table files.
> #1 seems like the best option. #2 is still vulnerable to config changes
> causing a problem
