--------------------------------------

             Summary: Changing Accumulo config can prevent locating root table files.
                 Key: ACCUMULO-1766
                 URL: https://issues.apache.org/jira/browse/ACCUMULO-1766
             Project: Accumulo
          Issue Type: Sub-task
            Reporter: Keith Turner
            Priority: Blocker
             Fix For: 1.6.0


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
