Getting error "Unable to find replication strategy class 'org.apache.cassandra.locator.simplestrategy" while creating keyspace

Question

I have installed "DataStax Distribution of Apache Cassandra 3.9.0". After opening cassandra CQL shell i ran the below command

Create keyspace KeyspaceName
with replicaton{'class':'simplestrategy','replication_factor': 1}

But i am getting an error:

Unable to find replication strategy class 'org.apache.cassandra.locator.simplestrategy'

Answer 1

The replication strategy class name is case sensitive in CQL, the correct syntax for a SimpleStrategy with replication factor of 1 is:

CREATE KEYSPACE my_keyspace
WITH replication = {'class': 'SimpleStrategy', 'replication_factor' : 1}

Answer 2

Cassandra is case sensitive so you should use SimpleStrategy instead of simplestrategy and no spaces in between are appreciated.
