Yes, but let's say you want to increment "f:a" and "f:b" in the row
"example". Your code requires 2 calls to increment() and would be seen
as two different puts so a reader could see "f:a" incremented but not
"f:b". It's the same for HBase's increment function, except it's going
to be much faster and won't suffer row lock problems.
