Josh Elser created ACCUMULO-3543:
------------------------------------

             Summary: ConstraintIT failed
                 Key: ACCUMULO-3543
                 URL: https://issues.apache.org/jira/browse/ACCUMULO-3543
             Project: Accumulo
          Issue Type: Bug
          Components: test
    Affects Versions: 1.6.2
            Reporter: Josh Elser
            Priority: Minor
             Fix For: 1.7.0, 1.6.3


In testing 1.6.2-rc3, I have {{ConstraintIT}} fail on me. Being a three-part test, the first
two part succeeded, while the third happened to fail.

Best as I can tell, the watcher for the constraint update on the third table didn't update
on the tserver before the test ran. The table

{noformat}

The table with id of '3', is the one that failed. The tserver never saw the user-specified
constraints before the test ran.

Add some logic to the test to prevent failures due to this race condition. We have ticket(s)
elsewhere for a more generalized "configuration consensus" feature, so I won't restate that
here.
