hadoop集群高可用配置及问题（下）-创新互联

之前已经把hdfs高可用配置好了，接下来配置yarn的高可用

1.之前集群规划已提到要在bigdata1和bigdata2上配置resourcemanger服务，在yarn-site.xml中添加

yarn.nodemanager.aux-servicesmapreduce_shuffleyarn.resourcemanager.ha.enabledtrueyarn.resourcemanager.cluster-idcluster-yarn1yarn.resourcemanager.ha.rm-idsrm1,rm2yarn.resourcemanager.hostname.rm1bigdata1yarn.resourcemanager.webapp.address.rm1bigdata1:8088yarn.resourcemanager.address.rm1bigdata1:8032yarn.resourcemanager.scheduler.address.rm1bigdata1:8030yarn.resourcemanager.resource-tracker.address.rm1bigdata1:8031yarn.resourcemanager.hostname.rm2bigdata2yarn.resourcemanager.webapp.address.rm2bigdata2:8088yarn.resourcemanager.address.rm2bigdata2:8032yarn.resourcemanager.scheduler.address.rm2bigdata2:8030yarn.resourcemanager.resource-tracker.address.rm2bigdata2:8031yarn.resourcemanager.zk-addressbigdata1:2181,bigdata2:2181,bigdata3:2181yarn.resourcemanager.recovery.enabledtrueyarn.resourcemanager.store.classorg.apache.hadoop.yarn.server.resourcemanager.recovery.ZKRMStateStoreyarn.nodemanager.env-whitelistJAVA_HOME,HADOOP_COMMON_HOME,HADOOP_HDFS_HOME,HADOOP_CONF_DIR,CLASSPATH_PREPEND_DISTCACHE,HADOOP_YARN_HOME,HADOOP_MAPRED_HOME	
	
	yarn.scheduler.minimum-allocation-mb512yarn.scheduler.maximum-allocation-mb4096yarn.nodemanager.resource.memory-mb4096yarn.nodemanager.pmem-check-enabledtrueyarn.nodemanager.vmem-check-enabledfalseyarn.log-aggregation-enabletrueyarn.log.server.urlhttp://bigdata1:19888/jobhistory/logsyarn.log-aggregation.retain-seconds604800

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
