             Summary: Improve validation of configuration and arguments with guava Predicates
                 Key: ACCUMULO-3956
                 URL: https://issues.apache.org/jira/browse/ACCUMULO-3956
             Project: Accumulo
          Issue Type: Improvement
            Reporter: Christopher Tubbs
            Assignee: Christopher Tubbs
             Fix For: 1.8.0


There's a few places in our code which could benefit from additional validation of arguments and configuration by using the built-in Guava Predicates. This makes some checks that we're doing a bit more readable, and enables us to do more expressive validation checks.

Specifically, I see room for improvement in our {{PropertyType}} validators (which currently do very limited regex validation) and, to a lesser degree, {{o.a.a.core.util.Validator}}.

I intend to replace these with proper Predicates to determine their validity.
