[SOLVED] Using cassandra phantom getting Cannot build a cluster without contact points

Using cassandra phantom getting Cannot build a cluster without contact points

I am using phantom 2.12.1 with cassandra 5.2.

I am running cassandra using docker and I keep getting this nasty error:

any idea what can cause that ?

Caused by: java.lang.IllegalArgumentException: Cannot build a cluster without contact points at com.datastax.driver.core.Cluster.checkNotEmpty(Cluster.java:119) at com.datastax.driver.core.Cluster.(Cluster.java:112) at com.datastax.driver.core.Cluster.buildFrom(Cluster.java:178) at com.datastax.driver.core.Cluster$Builder.build(Cluster.java:1335) at com.outworkers.phantom.connectors.DefaultSessionProvider.(DefaultSessionProvider.scala:41) at com.outworkers.phantom.connectors.CassandraConnection.provider$lzycompute(CassandraConnection.scala:41) at com.outworkers.phantom.connectors.CassandraConnection.provider(CassandraConnection.scala:41) at com.outworkers.phantom.connectors.CassandraConnection$Connector$class.provider(CassandraConnection.scala:91)

Solution

The error message is fairly explicit; your contact point ends up being passed an empty sequence as the hosts argument.

Check your configuration and make sure when you call ContactPoint inside your connector definition the sequence is not empty
