Not sure why there are java.lang.NoClassDefFoundError(s) for some classes like org.apache.hadoop.io.IOUtils
and org.apache.hadoop.util.StringUtils.  I never see it when I run the tests locally.

In some cases, the tests  could be passed even there is a NoClassDefFoundError.  For example,
see TestIPC in http://hudson.zones.apache.org/hudson/job/Hadoop-Patch/2410/console
