Aerospike Java spark connector

I am trying out aerospike as an alternative for cassandra. But I am not able to find a proper aerospark java connector or any example how to load and save rdd or dataframes in java (found lot of examples in scala.) .

Is there any tutorial or examples available for java Apache spark connector to load and save data to aerospike. (I found this connector GitHub - sasha-polev/aerospark: Aerospike Spark Connector but not enough documentation) .
