> If a tablet as multiple locations in the metadata table, the the master should take no
action on that tablet. I think the master may check for a tablet with future and loc, but
a tablet with loc and loc.    The total number of all loc and future entries for a tablet
should be zero or one.  You can have no entries, one loc or one future, corresponding to unassigned,
hosted or assigned, respectively.
