Hadoop 0.18.0 does not start on Mac OS X Leopard: NPE if no dfs.datanode.ipc.address value in the configuration
---------------------------------------------------------------------------------------------------------------

Project: Hadoop Common
Issue Type: Bug
Affects Versions: 0.18.0

The configuration files used are simply copied from the 0.17.2 version which
was working for me. Suddenly 0.18 does not even start.
