Hi, My requirement is to extract certain fields from json files, run queries on them and save the result to cassandra. I was able to parse json , filter the result and save the rdd(regular) to cassandra.
Now, when I try to read the json file through sqlContext , execute some queries on the same and then save the SchemaRDD to cassandra using saveToCassandra function, I am getting the following error: java.lang.NoSuchMethodException: Cannot resolve any suitable constructor for class org.apache.spark.sql.catalyst.expressions.Row Pls let me know if a spark SchemaRDD can be directly saved to cassandra just like the regular rdd? If that is not possible, is there any way to convert the schema RDD to a regular RDD ? Please advise.
