Hi again >From a little investigation I have performed I have observed the following. I assume the module responsible for this class is hadoop-yarn-common.
During RM init it crashes since it is looking for a class DefaultResourceCalculator in org.apache.hadoop.yarn.server.resourcemanager.resource.DefaultResourceCalculator, while the class is present in hadoop-yarn-common-3.0.0-SNAPSHOT.jar but under org.apache.hadoop.yarn.util.resource.DefaultResourceCalculator. Thus the RM crashes. Anybody knows how I can fix this? I would very grateful for any help. regards tmp 2013/8/11 Rob Blah <tmp5...@gmail.com> > Hi > > I have a strange problem, regarding missing class, the > DefaultResourceCalculator.
