Eli Collins commented on HADOOP-8159: ------------------------------------- Ah, I missed that the test was in HDFS, Colin, mind filing an HDFS jira for the test and we'll check this one it w/o the test and then do the HDFS jira with test? > 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 > Reporter: Colin Patrick McCabe > Assignee: Colin Patrick McCabe > Attachments: HADOOP-8159-b1.005.patch, HADOOP-8159.005.patch, > HADOOP-8159.006.patch, HADOOP-8159.007.patch, HADOOP-8159.008.patch > > > 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. -- This message is automatically generated by JIRA.
