wso2 - BAM 管理员密码更改后任务失败

Question

在 WSO2 BAM 4.1.0 中更改 admin 用户的默认密码后，任务失败并显示以下错误:

将密码恢复为其原始值可解决该问题。

如何更改管理员用户的密码并保持任务正常运行？

Answer 1

您是否更改了 hive 脚本 am_stats_analyzer 中的用户名、密码？默认为 admin/admin，检查 hive 脚本并相应地更新密码。属性如下；

"cassandra.ks.username"= "admin",
"cassandra.ks.password"= "xxxxx",

检查这是否能解决您的问题。
