This inconsistency

文件。不限于 jar 或 war 的启动方式。 3. 当作业服务器配置多网卡时，可通过设置系统变量 elasticjob.preferred.network. interface 指定网卡地址或 elasticjob.preferred.network.ip 指定 IP。ElasticJob 默认 获取网卡列表中第一个非回环可用 IPV4 地址。 运维平台和 RESTFul API 部署 (可选) preferred.network.interface 指定网卡或 elasticjob. preferred.network.ip 指定 IP 地址。 例如: 1. 指定网卡 eno1：-Delasticjob.preferred.network.interface=eno1。 2. 指定 IP 地址 192.168.0.100：-Delasticjob.preferred.network.ip=192 ip=192.168.0.100。 3. 泛指 IP 地址 (正则表达式) 192.168.*：-Delasticjob.preferred.network.ip=192.168.*。 10.13 zk 授权升级, 在滚动部署过程中出现实例假死, 回退到历史版本也 依然存在假死。 回答: 在滚动部署过程中, 会触发竞争选举 leader, 有密码的实例会给 zk 目录加密导致无密码的实例不可访问
