Cannot write RDD with a UDT that has a camel case column name defined in Cassandra. On the other hand reading does work.
Please find the attached code sample
Steps to repro:
1. Run create-table.cql to create a table with sample data
2. Run TestApp.scala, the reading works, writing fails.
Cassandra 3.0.15
Scala 2.11.8
Spark Cassandra Connector 2.0.5
