Keith Turner commented on ACCUMULO-1772:
----------------------------------------

It seems like tablets use the chooser to choose a dir, and then persist and use that dir from
then on?

> 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.
