I think Brock wrote this original code so he might know more, but yes it does
look like a bug to me. Only small comment is, you can annotate this method
with @VisibleForTesting annotation.
> Hiveptest is killing nodes where IP is reused after previous node termination

> Key: HIVE-15102
> URL: https://issues.apache.org/jira/browse/HIVE-15102
> Project: Hive
> Issue Type: Bug
> Components: Hive
> Affects Versions: 2.2.0
> Reporter: Sergio Peña
> Assignee: Sergio Peña
> Attachments: HIVE-15102.1.patch

>
> NO PRECOMMIT TESTS
> The Hiveptest framework has a background thread that runs every hour, and
> attempts to kill zombie nodes that are not being used by the test execution
> anymore.
> These killed nodes are kept in a list of terminated nodes, and next time the
> background thread is executed, it will attempt to kill all those nodes again
> because Hiveptest consider them as zombie nodes.
> The problem is that cloud providers can give you the same IP numbers for new
> nodes, and when the background thread runs, it will kill those nodes that may
> still be in used by Hiveptest.
