</property>1.启动整个集群 sbin/start-dfs.sh sbin/start-yarn.sh
2.在令一台resouceManager机器：启动resoruceManager sbin/yarn-daemon.sh start resourcemanager
3.问题：sbin/start-yarn.sh nodemanager 启动失败：java.lang.IllegalArgumentException: Cannot support recovery with an ephemeral server port. Check the setting of yarn.nodemanager.address
解决方式：参考文档:http://hadoop.apache.org/docs/r2.7.6/hadoop-yarn/hadoop-yarn-common/yarn-default.xml
