Might want to apply the same base64 encoding logic to the qualifier as you
would to the value.
I would think that if you base64 encode the value, you'd do all of the
other components as well. However, maybe I'm just being overly cautious. It's
probably fine to only do the value as a first-stab :)
> Create a FetchHBase Processor

> URL: https://issues.apache.org/jira/browse/NIFI-1784
> Project: Apache NiFi
> Issue Type: Improvement
> Reporter: Bryan Bende
> Assignee: Bryan Bende
> Priority: Minor
> Fix For: 1.2.0
>
>
> We should provide a processor to fetch a row from HBase. The processor should
> support receiving an incoming FlowFile and taking the row id to fetch from an
> attribute on the incoming, and should also be able to fetch a static row id.
