----------------------------------

             Summary: 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


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.
