yarn-site.xml 并使用zookeeper 来 管理resourcemanager的状态
| <?xml version="1.0"?> <configuration> <property> <name>yarn.resourcemanager.ha.enabled</name> <value>true</value> </property> <property> <name>yarn.resourcemanager.cluster-id</name> <value>cluster1</value> </property> <property> <name>yarn.resourcemanager.ha.rm-ids</name> <value>rm1,rm2</value> </property> <property> <name>yarn.resourcemanager.hostname.rm1</name> <value>master</value> </property> <property> <name>yarn.resourcemanager.hostname.rm2</name> <value>slave01</value> </property> <property> <name>yarn.resourcemanager.webapp.address.rm1</name> <value>master:8088</value> </property> <property> <name>yarn.resourcemanager.webapp.address.rm2</name> <value>slave01:8088</value> </property> <property> <name>yarn.resourcemanager.zk-address</name> <value>master:2181,slave01:2181,slave02:2181</value> </property> <!-- Site specific YARN configuration properties --></configuration> |
将配置同步到 master 和slave01 节点，然后启动rm
hadoop-2.7.2/sbin/yarn-daemon.sh start resourcemanager
查看节点状态
hadoop-2.7.2/bin/yarn rmadmin -getServiceState rm1
hadoop-2.7.2/bin/yarn rmadmin -getServiceState rm2
