[jira] [Created] (HADOOP-8159) NetworkTopology: getLeaf should check for invalid topologies

NetworkTopology: getLeaf should check for invalid topologies
------------------------------------------------------------

                 Key: HADOOP-8159
                 URL: https://issues.apache.org/jira/browse/HADOOP-8159
             Project: Hadoop Common
          Issue Type: Bug
    Affects Versions: 1.0.0
            Reporter: Colin Patrick McCabe
            Assignee: Colin Patrick McCabe
             Fix For: 1.0.0


Currently, in NetworkTopology, getLeaf doesn't do too much validation on the InnerNode object itself. This results in us getting ClassCastException sometimes when the network topology is invalid. We should have a less confusing exception message for this case.
