这篇文章主要介绍了hadoop-005-YARN HA如何配置，具有一定借鉴价值，感兴趣的朋友可以参考下，希望大家阅读完这篇文章之后大有收获，下面让小编带着大家一起了解一下。
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
[jxlgzwh@slave01 ~]$ hadoop-2.7.2/sbin/yarn-daemon.sh start resourcemanager
starting resourcemanager, logging to /home/jxlgzwh/hadoop-2.7.2/logs/yarn-jxlgzwh-resourcemanager-slave01.out
