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.
