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 utility to decommission dfs uris

> 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.
