Keith Turner commented on ACCUMULO-708:
---------------------------------------
I applied the patch and have been unable to get the unit test to run. Keep

bq. Where should this be documented? User guide, readme, etc?
Maybe add something to the users guide and add an example that shows off what
can be done.
