The labels are used for authorizations certainly, but they're used to
filter specific cells, too, right? E.g. if tag 'A' and tag 'B' are associated
with a user, then the user can access following cells:
- Tagged with 'A'
- Tagged with 'A' and 'B'
- Tagged with 'B'
In that case, if NiFi user would like to fetch/scan only cells tagged with
'B', the name of the property 'Authorizations' does not sound perfect to me. It
would make more sense if we called it simply 'Visibility Labels'. How do you
think?

> HBase supports visibility labels, but you can't use them from NiFi because
> there is no way to set them. The existing processors and services should be
> upgraded to handle this capability.
