Hi,
Since, the cassandra object is not serializable you can't open the
connection on driver level and access the object inside foreachRDD (i.e. at
worker level).
You have to open connection inside foreachRDD only, perform the operation
and then close the connection.
For example:
wordCounts.foreachRDD( rdd => {
val arr = rdd.toArray
OPEN cassandra connection
store arr
CLOSE cassandra connection
})
Thanks
