Date Mon, 14 Mar 2016 16:59:33 GMT
Josh Elser created ACCUMULO-4163:

             Summary: ZooZap should deal with /tracers being missing
                 Key: ACCUMULO-4163
             Project: Accumulo
          Issue Type: Bug
          Components: zookeeper
    Affects Versions: 1.7.1
            Reporter: Josh Elser

2016-03-14 16:57:15,316 [util.ZooZap] ERROR: Exception running zapDirectory.

This shouldn't be an error that is propagated to the user to see. We should know that it's
ok if '/tracers' doesn't exist and move on silently
