How to use spring data cassandra & elasticsearch configuration

I'm trying to use both Spring Data Cassandra & Spring Data ElasticSearch in an Spring Boot application. I already put Cassandra Repository & ElasticSearch Repository in different packages.

@EnableElasticsearchRepositories(basePackages = "com.my.app.es.repository")
public class ElasticsearchConfig {
   ...
}

@EnableCassandraRepositories(basePackages = { "com.my.app.cassandra.repository" })
public class CassandraConfig extends AbstractCassandraConfiguration {
   ...
}

When I tried to run, I got the following exception::

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'converter' defined in class path resource [com/my/app/config/CassandraConfig.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.data.cassandra.convert.CassandraConverter]: Factory method 'converter' threw exception; nested exception is java.lang.IllegalStateException: @Bean method CassandraConfig.mappingContext called as a bean reference for type [org.springframework.data.cassandra.mapping.CassandraMappingContext] but overridden by non-compatible bean instance of type [org.springframework.data.elasticsearch.core.mapping.SimpleElasticsearchMappingContext].

I also faced the same issue, I was using this to created CassandraConverter() object and using the constructor with CassandraMappingContext which was creating the issue.

Issue:-

@Bean
    public CassandraMappingContext mappingContext() {
        return new BasicCassandraMappingContext();
    }

    @Bean
    public CassandraConverter converter() {
        return new MappingCassandraConverter(mappingContext()); //Remove this and call MappingCassandraConverter() with passing any arguement.
    }

To fix this i replaced above with:-

@Bean
    public CassandraConverter converter() throws ClassNotFoundException {
        return new MappingCassandraConverter();
    }

And rest piece of code remains same of setting this converter in CassandraSessionFactoryBean()

If your problem is not solved please provide the snippet, i will provide the correct configuration.
