We're using the latest Cloudera release, hadoop-0.20-0.20.2+737. The MaxTemperature example is returning a runtime error: java.lang.RuntimeException: Error in configuring object.
The MaxTemperature example in chapter 2 must be run in stand-alone mode. We installed the conf-pseudo RPM and this example is not configured properly for the JobTracker. When we switched to stand-alone mode, it ran without complaint.
