>             Project: Apache NiFi

>            Priority: Major
>
> NiFi currently has processors for storing and retrieving cells/rows in HBase, 
> but there is no mechanism for deleting records and/or tables.
> I'm not sure if a single DeleteHBase processor could accomplish both, that 
> can be discussed under this Jira (and can be split out if necessary).
