dolphinscheduler报错：Connect to 192.168.xx.xx:8088 [192.168.xx.xx/110.173.196.1] failed: connect timed out

报错信息：

在dophin中抽取mysql的数据到hive中报错

[ERROR] 2023-10-20 15:33:10.461 org.apache.dolphinscheduler.common.utils.HttpUtils:[73] - Connect to 192.168.xx.xx:8088 [192.168.xx.xx/110.173.196.1] failed: connect timed out

分析：

yarn是单节点部署，在conf/config/install_config.conf配置中没有把yarnHaIp设置为空

 

解决：

yarnHaIps=""

注意：还要修改conf/common.properties中yarnHaIps配置，如果启动任务查看worker日志还是报错建议卸载重新安装。
