DATA_SOURCE_NOT_FOUND Failed to find the data source: com.crealytics.spark.excel

Question

I'm trying to submit a java spark program with the package crealytics.spark-excel.

The java file looks like this:

package org.example;

import org.apache.spark.sql.Dataset;
import org.apache.spark.sql.Row;
import org.apache.spark.sql.SparkSession;

import com.crealytics.spark.excel.*;

public class Main {
    public static void main(String[] args) {
        SparkSession spark = SparkSession.builder()
                .appName("Spark_Excel")
                .master("local")
                .getOrCreate();
        String filePath = "/home/arman/Desktop/resources/example_XLSX_5000.xlsx";
        Dataset<Row> dataset = spark.read().format("com.crealytics.spark.excel")
                .option("header", "true")
                .load(filePath);
        dataset.show();

        dataset.write()
                .format("excel") // Or .format("excel") for V2 implementation
                .option("header", "true")
                .partitionBy("Country")
                .save("/home/arman/Desktop/output/partitioned");

        spark.stop();
    }
}

The pom.xml looks like this:

It's working correctly, if I run the java class from intellij idea but using spark-submit --class org.example.Main spark-excel-1.0-SNAPSHOT.jar I become the following error:

Exception in thread "main" org.apache.spark.SparkClassNotFoundException: [DATA_SOURCE_NOT_FOUND] Failed to find the data source: com.crealytics.spark.excel. Please find packages at `https://spark.apache.org/third-party-projects.html`.

I have tried with both formats "com.crealytics.spark.excel" and "excel" and tried with different versions of the dependencies

Answer 1

spark-excel_2.12 is not included in the driver classpath.

You can either:

• Include the spark excel dependency in your application JAR.
• Pass the dependency at runtime. Either pass --packages com.crealytics:spark-excel_2.12:3.4.1_0.19.0 in your spark-submit command, or by passing the configuration spark.jars.packages set to the maven coordinates of the dependency.
