Issue:
Not able to execute the Transformer pipeline in Cluster-Mode, although in client mode it works fine.
Solution:
If it is the case that keytab/principal is configured in the application, although the Kerberos shouldn't be started. Check the following steps:
1) Comment the line kerberos.client.enabled= true in the transformer.properties file.
2) Check your Transformer version if it contains the property called kerberos.client.alwaysResolveProperties in the transformer.properties file. If it is not present add this line and set the value to true( kerberos.client.alwaysResolveProperties=true) .
This property is to allow admins to specify a system-wide keytab/principal in the properties file, but still not start the Kerberos client. (i.e. the login process to the KDC),
3) Restart Transformer.
