Description
Attempting to use version 2.0.0-M3 of the datastax/spark-cassandra-connector to select the most recent version of each partition key using the Cassandra 3.6 and later PER PARTITION LIMIT option fails. I've tried using all the Cassandra Java RDD's and Spark Sql with and without partition key equality constraints. All attempts have failed due to syntax errors and/or start/end bound restriction errors.
The BrentDorsey/cassandra-spark-job repo contains working code that demonstrates the error. Clone the repo, create the keyspace and table locally and supply connection information then run main.
