Tasks fail after BAM admin password change

Question

After changing the default password for admin user in WSO2 BAM 4.1.0, tasks fail with the following error:

Reverting back the password to its original value solves the issue.

How do I change the password for the admin user and keep the tasks working?

Answer 1

Have you changed the username, password in the hive script am_stats_analyzer? The defaults are admin/admin, check the hive script and update the password accordingly. The property is as follows;

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

Check if that fixes your issue.

Answer 2

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 !
