I am new to Spark and trying to read a CSV file using Java maven project but getting ArrayIndexOutOfBoundsException error.

Dependencies:

 <dependencies>
 <!-- https://mvnrepository.com/artifact/org.apache.spark/spark-core -->
 <dependency>
 <groupId>org.apache.spark</groupId>
 <artifactId>spark-core_2.12</artifactId>
 <version>2.4.0</version>
 </dependency>

 <!-- https://mvnrepository.com/artifact/org.apache.spark/spark-sql -->
 <dependency>
 <groupId>org.apache.spark</groupId>
 <artifactId>spark-sql_2.12</artifactId>
 <version>2.4.0</version>
 </dependency>
</dependencies>

Code:

SparkSession spark = SparkSession
 .builder()
 .appName("Java Spark SQL Example")
 .config("spark.master", "local")
 .getOrCreate();

 //Read file
 Dataset<Row> df = spark.read()
 .format("csv")
 .load("test.csv");

CSV File

name,code
A,1
B,3
C,5

Here is stacktrace

The paranamer version referred in Spark 2.4.0 is 2.7 which is causing the issue. Adding following dependency before the spark-core/ spark-sql solved the issue for me.

<dependency>
 <groupId>com.thoughtworks.paranamer</groupId>
 <artifactId>paranamer</artifactId>
 <version>2.8</version>
</dependency>

I meet the same problem, but when I tried scala, this problem solved!

val tp = StructType(Seq(StructField("name", DataTypes.StringType), StructField("code", DataTypes.IntegerType)))

val df = spark.read.format("csv").option("header", "true").schema(tp).load("test.csv")
