在 WSO2 BAM 4.1.0 中更改管理员用户的默认密码后，任务失败并出现以下错误：

将密码恢复为原始值可以解决问题。

如何更改管理员用户的密码并保持任务正常运行？

In order to solve the issue I had to perform the following steps:

  • edit the file [BAM_HOME]/repository/conf/etc/cassandra-auth.xml and change the password value to the new password.
  • edit the file [BAM_HOME]/repository/conf/datasources/master-datasources.xml and change the password value of the WSO2BAM_CASSANDRA_DATASOURCE datasource to the new password.
  • restart the BAM: the Hive tasks now run without errors.

where the new password is the password I assigned to the admin user.

Moreover, the Main \ Manage \ Cassandra Keyspaces \ List page in the BAM UI, which was raising the following error, is now fixed:

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

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

“cassandra.ks.username”=“管理员”，“cassandra.ks.password”=“xxxxx”，

检查是否可以解决您的问题。

抱歉我没能早点跟进这个问题，无论如何很高兴你的问题现在已经解决了。！继续尝试 BAM，如果遇到任何问题，请不要犹豫。

谢谢，沙里克。
