Sean Busbey commented on ACCUMULO-1000:
---------------------------------------

We should definitely allow passing of auths, so -1 to #2.

#4 would be consistent with what we do for the rest of the Mutation API, which I like, but I agree that it smells of confused users down the road.

#1 seems most supportable, since it makes clear that you're only checking what you're allowed to see. As a bonus a change from required -> optional would be non-breaking, but not vice-versa, so we could change to #4 or #3 down the line if operational use finds them compelling.

> Add support to mutation for compare and set operations.  This would allow user to specify that a row must contain certain data for a mutation to be applied.
