JPS stopped each node is normal after the restart still normal is log of all nodes have the wrong hope everybody can help me to analyze analysis also learn
Building cluster is not the first time to rule out the problem of configuration files (I am in my normal configuration files in the cluster configuration, hadoop version also like my normal cluster) (if the problem will solve the unified solution is given, after this kind of problems people refer to!!!!! )
