Eric Newton commented on ACCUMULO-1772:
---------------------------------------

The volume chooser is pluggable.  A chooser which would never choose the last volume would
eventually decommission it.

> Need to support situation where a user would like to decommission one uri in instance.volumes.
 After decommissioning, Accumulo would no longer create files there.  However it would still
reference files created there in the past.
> One way to support this is to have tablet check their configured uri is still in the
config.   This could be done at tablet load time or even at compaction time.
