Jean Georges Perrin updated SPARK-26146:
----------------------------------------
Description:
Ingestion of a CSV file seems to fail with Spark v2.4.0 and Scala v2.12, where
it works ok with Scala v2.11.
When running a simple CSV ingestion like:{{ }}
{code:java}
// Creates a session on a local master
SparkSession spark = SparkSession.builder()
.appName("CSV to Dataset")
.master("local")
.getOrCreate();
// Reads a CSV file with header, called books.csv, stores it in a dataframe
Dataset<Row> df = spark.read().format("csv")
.option("header", "true")
.load("data/books.csv");
{code}
With Scala 2.12, I get:
{code:java}
Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 10582

Where it works pretty smoothly if I switch back to 2.11.
Full example available at
[https://github.com/jgperrin/net.jgp.books.sparkWithJava.ch01.] You can modify
pom.xml to change easily the Scala version in the property section:
{code:java}
<properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
<java.version>1.8</java.version>
<scala.version>2.11</scala.version>
<spark.version>2.4.0</spark.version>
</properties>{code}
(ps. It's my first bug submission, so I hope I did not mess too much, be
tolerant if I did)
