yarn.nodemanager.aux-services mapreduce_shuffle yarn.resourcemanager.ha.enabled true yarn.resourcemanager.cluster-id cluster-yarn1 yarn.resourcemanager.ha.rm-ids rm1,rm2 yarn.resourcemanager.hostname.rm1 bigdata1 yarn.resourcemanager.webapp.address.rm1 bigdata1:8088 yarn.resourcemanager.address.rm1 bigdata1:8032 yarn.resourcemanager.scheduler.address.rm1 bigdata1:8030 yarn.resourcemanager.resource-tracker.address.rm1 bigdata1:8031 yarn.resourcemanager.hostname.rm2 bigdata2 yarn.resourcemanager.webapp.address.rm2 bigdata2:8088 yarn.resourcemanager.address.rm2 bigdata2:8032 yarn.resourcemanager.scheduler.address.rm2 bigdata2:8030 yarn.resourcemanager.resource-tracker.address.rm2 bigdata2:8031 yarn.resourcemanager.zk-address bigdata1:2181,bigdata2:2181,bigdata3:2181 yarn.resourcemanager.recovery.enabled true yarn.resourcemanager.store.class org.apache.hadoop.yarn.server.resourcemanager.recovery.ZKRMStateStore yarn.nodemanager.env-whitelist JAVA_HOME,HADOOP_COMMON_HOME,HADOOP_HDFS_HOME,HADOOP_CONF_DIR,CLASSPATH_PREPEND_DISTCACHE,HADOOP_YARN_HOME,HADOOP_MAPRED_HOME
yarn.scheduler.minimum-allocation-mb 512 yarn.scheduler.maximum-allocation-mb 4096 yarn.nodemanager.resource.memory-mb 4096 yarn.nodemanager.pmem-check-enabled true yarn.nodemanager.vmem-check-enabled false yarn.log-aggregation-enable true yarn.log.server.url http://bigdata1:19888/jobhistory/logs yarn.log-aggregation.retain-seconds 604800
2.启动hdfs
3.启动yarn
在bigdata1上启动yarn
4.查看服务状态
5.web端查看yarn状态:********(ip地址):8088
到此,Hadoop高可用配置就完成了
