Keith Turner commented on ACCUMULO-2793:
----------------------------------------

Some sort of confirmation on add-volumes would be nice.

Maybe the scenario where volumes being replaced still exist in 
{{instance.volumes}} should cause a warning to be logged, or even failure.

> Clean up handling of moving HDFS under Accumulo from non-HA to HA

> We added a util to handle cluster maintenance (such as going from non-HA HDFS 
> to HA HDFS) in ACCUMULO-1832.
> It should be added to section 13.5 Tools in the user manual, and a reference 
> to that section should be added in the section 12 explanation of the impact 
> of supporting multi-volume setups.
