DynamicServiceHandler cannot be cast to com.cloudera.cmf.service.RollingRestartProvider

Hello:

I have created CSD for a service by referring the following wiki page by cloudera https://github.com/cloudera/cm_ext/wiki/Service-Descriptor-Language-Reference.

This CSD service has three roles inside it. two non-worker and one worker roles. And I have configured those roles to take part in rolling restart, as per the wiki.

But during up-gradation of CDH, I got exception as

Failed due to java.lang.ClassCastException: com.cloudera.cmf.service.csd.components.DynamicServiceHandler cannot be cast to com.cloudera.cmf.service.RollingRestartProvidere

And in cloudera-scm-server logs I get logs:
