I am trying to set up Apache Atlas with CosmosDB Cassandra API with Strong as the default consistency level. During startup after ~10 seconds I get this null pointer exception:-

In cosmosdb cassandra explorer I can see some of tables created:-
What is the reason for this exception and how should I resolve it ? It works fine when I try to run it with a simple Cassandra instance.
