----------------------------------------------
[~ndimiduk] sure. I've set the "Affects versions" accordingly. I don't see any
comments I must address there (unless I'm missing something). Are you +1 on it?
> Ability to run mini cluster using pre-determined available random ports
> -----------------------------------------------------------------------

> Key: HBASE-23259
> URL: https://issues.apache.org/jira/browse/HBASE-23259
> Project: HBase
> Issue Type: Test
> Components: test
> Affects Versions: 3.0.0, 1.4.12, 2.2.3
> Reporter: Bharath Vissapragada
> Assignee: Bharath Vissapragada
> Priority: Major
>
> As noted in the code reviews for HBASE-18095, we need the ability to run the
> mini-cluster using a pre-determined set of random (and available) port
> numbers. When I say pre-determined, I mean the test knows these ports even
> before starting the mini cluster.
> In short, the workflow is something like,
> {noformat}
> List<Ports> ports = getRandomAvailablePorts();
> startMiniCluster(conf, ports);
> {noformat}
> The reason we need this is that certain configs introduced in HBASE-18095
> depend on the ports on which the master is expected to serve the RPCs. While
> that is known for regular deployments (like 16000 for master etc), it is
> totally random in the mini cluster tests. So we need to know them before hand
> for templating out the configs.
