Spring Cassandra driver always connected to localhost

Question

im trying to connect my Spring Boot app to a Cassandra 2.2.8 cluster on EC2 instances (2 nodes). my use is tracing with Sleuth and Zipkin.

when the tracing start, the driver always point to localhost :

com.datastax.driver.core.Cluster : New Cassandra host localhost/127.0.0.1:9042 added

this is my application.properties

spring.datasource.url=jdbc:cassandra://url-node-1:9042
spring.datasource.contactPoints=url-node-1,url-node-2
zipkin.storage.type=cassandra
spring.datasource.initialize=true
spring.datasource.continue-on-error=true
spring.sleuth.enabled=false

and this is my pom.xml :

<dependency>
        <groupId>io.zipkin.java</groupId>
        <artifactId>zipkin-autoconfigure-storage-cassandra</artifactId>
        <version>1.17.1</version>

Zipkin's connection to cassandra is independent from the normal spring setup. We use some very specific setup. you'll want to set properties in the namespace of zipkin.storage.cassandra
