[jira] [Created] (ACCUMULO-3233) Random port for ZK in MiniAccumulo might not be unique

Josh Elser created ACCUMULO-3233:
------------------------------------

             Summary: Random port for ZK in MiniAccumulo might not be unique
                 Key: ACCUMULO-3233
                 URL: https://issues.apache.org/jira/browse/ACCUMULO-3233
             Project: Accumulo
          Issue Type: Improvement
          Components: mini
    Affects Versions: 1.6.1, 1.5.2
            Reporter: Josh Elser
            Assignee: Josh Elser
             Fix For: 1.5.3, 1.6.2, 1.7.0


To start ZooKeeper in a way that won't interfere with other processes on the node, we have to choose a "random" port on the node and then configure Accumulo with that port (as we don't have a means to get the random port that ZooKeeper itself would bind to).

The problem is that there is a delay between our choosing of a random port and ZooKeeper binding to that port which introduces a race condition.
