如何将 avro 文件读取为 Java Spark 中的对象列表

Question

I have an avro file which i want to read and operate on after converting it to its representative object

I've tried loading it using RDD and DataSet in Java Spark but in both cases i'm unable to convert to the required object

As DataSet

Dataset<MyClass> input = sparkSession.read().format("com.databricks.spark.avro").load(inputPath)
                .as(Encoders.bean(MyClass.class)); 

This fails with error "Cannot have circular references in bean class, but got the circular reference of class class org.apache.avro.Schema"

As RDD

JavaRDD<String> input = sparkContext.textFile(inputPath);

How can I convert this RDD object to RDD object or Dataset object?

I'm pretty new to this so pardon me if I'm missing something basic but unable to find a working solution.

This is solved by using SparkAvroLoader from https://github.com/CeON/spark-utils
