Subject [jira] [Created] (ACCUMULO-670) BatchWriters do not track Throwables beyond Constraint Violations

             Summary: BatchWriters do not track Throwables beyond Constraint Violations
                 Key: ACCUMULO-670

had errors, which key extents had errors, and what ConstrainViolations we saw, but we don't

a Collection or Set of the Throwables we see so client code can do proper case checking as
