i am trying to follw this tutorial https://dzone.com/articles/databricks-delta-lake-using-java So i want to use spark with delta lake, but for my storage i use minio and not hdfs or s3 (But it is incorporated the same way). Maybe someone can help me with my problem, so here is my code:
package minIO;
import java.io.IOException;
import java.util.ArrayList;
import java.util.List;
import org.apache.spark.sql.DataFrameWriter;
import org.apache.spark.sql.Dataset;
import org.apache.spark.sql.Encoder;
import org.apache.spark.sql.Encoders;
import org.apache.spark.sql.Row;
import org.apache.spark.sql.SparkSession;
public class MinIOConnector {
public static void main(String[] args) throws IOException {
SparkSession spark = SparkSession.builder()
.appName("Spark Excel file conversion")
.config("spark.master", "local")
.config("spark.sql.extensions", "io.delta.sql.DeltaSparkSessionExtension")
.config("spark.sql.catalog.spark_catalog", "org.apache.spark.sql.delta.catalog.DeltaCatalog")
.config("spark.hadoop.fs.s3a.access.key", "")
.config("spark.hadoop.fs.s3a.secret.key", "")
.config("spark.hadoop.fs.s3a.endpoint", "")
.config("spark.databricks.delta.retentionDurationCheck.enabled", "false")
.config("spark.hadoop.fs.s3a.aws.credentials.provider", "org.apache.hadoop.fs.s3a.SimpleAWSCredentialsProvider")
.config("spark.sql.warehouse.dir", "file://./sparkapp")
.config("spark.hadoop.io.native.lib.available", "false")
.config("spark.hadoop.fs.file.impl", "org.apache.hadoop.fs.LocalFileSystem")
.getOrCreate();
List<Employee> empList = new ArrayList<Employee>();
Employee emp = new Employee();
emp.setEmpId("1234");
emp.setEmpName("kiran");
emp.setDeptName("Design dept");
empList.add(emp);
emp = new Employee();
emp.setEmpId("3567");
emp.setEmpName("raju");
emp.setDeptName("IT");
empList.add(emp);
Encoder<Employee> employeeEncoder = Encoders.bean(Employee.class);
Dataset<org.apache.spark.sql.Row> empDF = spark.createDataset(empList, employeeEncoder).toDF();
DataFrameWriter<Row> x = empDF.write().format("delta");
x.save("s3a://test/test");
System.out.println("after write");
empDF = spark.read().format("delta").load("s3a://test/test");
empDF.show();
}
}
