I am trying to add the prerequisites as pointed on the [Tutorial: Set up cross-cluster replication | Elasticsearch Guide [7.13] | Elastic](https://www.elastic.co/guide/en/elasticsearch/reference/current/ccr-getting-started.html#ccr-getting-started-prerequisites) so I added to my k8s elastic yaml in the local cluster:

ccr\_user:  
cluster:  
- manage\_ccr  
indices:  
- names: ['follower-index']  
privileges:  
- monitor  
- read  
- write  
- manage\_follow\_index

I am getting:  
uncaught exception in thread [main]  
org.elasticsearch.bootstrap.StartupException: java.lang.IllegalArgumentException: unknown setting [cluster.ccr\_user.cluster] please check that any required plugins are installed, or check the breaking changes documentation for removed settings

I added to the xpack section and I was getting:  
"org.elasticsearch.bootstrap.StartupException: java.lang.IllegalArgumentException: unknown setting [xpack.ccr\_user.cluster] please check that any required plugins are installed, or check the breaking changes documentation for removed settings"

So I am lost. Should it be part of the xpack? and if it is why is not taking it and if it is not part. What plugins I need to add?

Thanks in advance

Can you share your Elasticsearch log from startup to when you see that?
