Christopher Tubbs resolved ACCUMULO-2439.
-----------------------------------------
Resolution: Won't Fix
I'm closing this issue (and the related open review) as "Won't Fix" for now.
The consensus from the lengthy [mailing list
discussion|http://apache-accumulo.1065345.n5.nabble.com/quot-NOT-quot-operator-in-visibility-string-td7949.html]
appears to be against this feature (at least, in the current form).
To revisit this, please open further discussion on the [email protected]
mailing list.
> Add a NOT (!) operator to ColumnVisibility

> Key: ACCUMULO-2439

> Project: Accumulo

> This patch adds a NOT "!" operator to ColumnVisibility.
> The syntax is as follows:
> !a
> (!a)&(!b)
> a&(!b)
> a&(!(b|c))
> Because of the nature of the current visibility parsing algorithm the
> additional parentheses are required.
> In the shell, the "\!" requires escaping. This is due to how JLine parses the
> command and attempts to substitute "!" with history.
