I am looking into adding conditional mutations to Accumulo 1.6. that would
support this.

https://issues.apache.org/jira/browse/ACCUMULO-1000

In the design document I suggested a method called putCondition() and if
the value was null, thats mean that the user expected it to be absent.   I
don't really like that API for specifying expected absence.
