[jira] [Created] (HDFS-3073) NetworkTopology::getLeaf should check for invalid topologies

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

                 Key: HDFS-3073
                 URL: https://issues.apache.org/jira/browse/HDFS-3073
             Project: Hadoop HDFS
          Issue Type: Bug
    Affects Versions: 1.0.0
            Reporter: Colin Patrick McCabe
            Assignee: Colin Patrick McCabe


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