> checkAndPut should integrate with MVCC, similar to how HBASE-4583 fixed
> appends and increments.
> Also need a test, here's one we could use (originally proposed in HBASE-7051):
> The current value of some cell is 10.
> I issue two concurrent requests:
> A) a check and put where check value = 10, put value = 11
> B) a put where put value = 50
> The only result at the end of these operations that seems reasonable to me is
> the value of the cell being 50. If A occurred first (ACID wise), then our
> values go 10->11->50. If B occurred first, then our values go 10->50 (and the
> checkAndPut fails)
