It says "Only written when a flowfile contains multiple deletes." but the
attribute is written when a FlowFile only contains single row id. It would be
more accurate if we say "Only written when deleting Row IDs from flowfile
content."
> Add DeleteHBase processor(s)

> Key: NIFI-3538
> URL: https://issues.apache.org/jira/browse/NIFI-3538
> Project: Apache NiFi
> Issue Type: New Feature
> Components: Extensions
> Reporter: Matt Burgess
> Assignee: Mike Thomsen
> 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).
