Provide optional stricness for SummingCombiner
----------------------------------------------

                 Key: ACCUMULO-319
                 URL: https://issues.apache.org/jira/browse/ACCUMULO-319
             Project: Accumulo
          Issue Type: Improvement
            Reporter: John Vines
             Fix For: 1.4.0


Currently the summing combiner will throw an error on a format exception. This is great for
high precision combining to ensure that all data is included. However, there is a potential
use case for people who just want data combined and do not want a wrench thrown in the system
for a bad value. Rather then having to write a whole different combiner, we should add a configuration
option to allow lossy combining which does not take into account bad value.
