你到目录下找下对应进程的日志观察下，里面报什么错了

  hadoop-hadoop-datanode-hadoop000.log    hadoop-hadoop-secondarynamenode-hadoop000.log    yarn-hadoop-nodemanager-hadoop000.out
  hadoop-hadoop-datanode-hadoop000.out    hadoop-hadoop-secondarynamenode-hadoop000.out    yarn-hadoop-nodemanager-hadoop000.out.1

  hadoop-hadoop-namenode-hadoop000.out.1  yarn-hadoop-nodemanager-hadoop000.log
  里面没有相关节点的日志，这是让我很奇怪的

  你hadoop000机器和你的IP映射关系检查下是否对？
