Subject [jira] [Commented] (HADOOP-8159) NetworkTopology: getLeaf should check for invalid topologies
Date Thu, 22 Mar 2012 20:34:23 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-8159?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13235993#comment-13235993

Aaron T. Myers commented on HADOOP-8159:

bq. Not sure what's up with Jenkins. It claims "The patch does not appear to apply with p0
to p2" but the patch applies cleanly for me on trunk on the latest rev.

The patch is cross-project, which test-patch can't handle.

> 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.
