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.
