Each Cassandra node is an Elasticsearch shard for each indexed keyspace. Unlike Elasticsearch, sharding depends on the number of nodes in the datacenter, and the number of replica is defined by your keyspace Replication Factor . Elasticsearch numberOfShards is just information about the number of nodes.
