1, 其中需要注意的是yarn.resourcemanager.ha.id是对于每个rm节点单独配置的
2,配置后,首先使用前台方式启动查看是否配置正确
yarn resourcemanager
3,没问题后使用服务启动命令,注意每个rm节点都需要启动
yarn-daemon.sh start resourcemanager
4,验证:正常情况下,rm1(ip=103)节点是active节点,rm2(ip=104)节点为备份节点
看图,这是正常启动结果:
杀掉rm1上的进程,并重新启动,此时再看:
发现rm2已经成为活动节点。如果杀掉rm2上的进程并重新启动,rm1就会切换回active节点,而rm2切换回standby状态。
