我想读avro文件

val conf = new SparkConf().setAppName("Nightmare").setMaster("local")
val sc = new SparkContext(conf)
sc.setLogLevel("Error")
val spark= SparkSession.builder().getOrCreate()
import spark.implicits._
//Step 1-2 read avro file
println("Step 1-2")
val df1 = spark.read
  .format("com.databricks.spark.avro")
  .option("multiline","true")
  .load("file:///D:/bigdata_tasks/nightmare.avro")
//step 3-4 Hit the url --- Convert it to dataframe -- https://randomuser.me/api/0.8/?results=1000 - df2
println("Step 3-5")
val html =Source.fromURL(" https://randomuser.me/api/0.8/?results=1000")
val rdddata=html.mkString
//convert string to rdd
val paralleldata=sc.parallelize(List(rdddata))
val df2= spark.read.json(paralleldata)
df2.printSchema()
df2.show()

运行后出现异常:
线程“main”java.lang.noclassdeffounderror中出现异常:org/apache/spark/sql/catalyst/structfilters
我还尝试了以下代码:

val df1 = spark.read
      .format("avro")
      .option("multiline","true")
      .load("file:///D:/bigdata_tasks/nightmare.avro")

但同样的例外是给予。我的spark版本是2.12。我应该更新spark版本吗?

最可能的原因是混合了spark版本-您的avro库来自spark 3.1.1,而spark的核心来自spark 3.0.1(通常最好将版本声明为属性,这样所有组件都可以有一个版本)。另外,删除不必要的依赖项,如spark xml、aws sdk等。
还要检查scala版本
