> Paste the following into your shell:
> {noformat}
> deletetable test
> createtable test
> setiter -t test -p 16 -scan -n test_1 -class
> org.apache.accumulo.core.iterators.user.SummingCombiner
> count:a
> STRING
> setiter -t test -p 17 -scan -n test_2 -class
> org.apache.accumulo.core.iterators.user.SummingCombiner

> insert row count a 1
> insert row count b 1
> insert row count b 1
> insert row count b 1
> insert row count c 1
> scan
> {noformat}
> I expect:
> {noformat}
> row count:a [] 2
> row count:b [] 3
> row count:c [] 1
> {noformat}
> But instead, I get this:
> {noformat}
> row count:a [] 12
> {noformat}
