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：

将密码恢复为原始值可以解决问题。

如何更改 admin 用户的密码并保持任务正常运行？

Answer 1

您是否更改了配置单元脚本am_stats_analyzer中的用户名和密码？默认值为admin / admin，检查hive脚本并相应地更新密码。该物业如下;

“cassandra.ks.username”=“admin”， “cassandra.ks.password”=“xxxxx”，

检查是否可以解决您的问题。

Answer 2

为了解决这个问题，我必须执行以下步骤：

修改文件[BAM_HOME]/repository/conf/etc/cassandra-auth.xml并将password值更改为新密码。
修改文件[BAM_HOME]/repository/conf/datasources/master-datasources.xml并将password数据源的WSO2BAM_CASSANDRA_DATASOURCE值更改为新密码。
重新启动BAM：Hive任务现在可以正常运行。

新密码是我分配给 admin用户的密码。

此外，BAM UI中的 Main \ Manage \ Cassandra Keyspaces \ List 页面现在已修复：

org.wso2.carbon.cassandra.mgt.ui.CassandraAdminClientException: Error retrieving keyspace names !
(...)
Caused by: org.apache.axis2.AxisFault: InvalidRequestException(why:You have not logged in)
(...)

Answer 3

抱歉，我之前无法跟进这个问题，反正很高兴你的问题现在已经整理好了。继续尝试BAM，如果遇到任何问题，请不要犹豫。

谢谢， Shariq。
