NoClassDefFoundError
Key: SPARK-43843
URL: https://issues.apache.org/jira/browse/SPARK-43843
Project: Spark
Issue Type: Bug
Components: SQL
Affects Versions: 3.5.0
Reporter: Bruce Robbins
I launched spark-shell as so:
{noformat}
bin/spark-shell --driver-memory 8g --jars `find . -name "spark-avro*.jar" |
grep -v test | head -1`
{noformat}
I got the below error trying to create an AVRO file:
{noformat}
scala> val df = Seq((1, 2), (3, 4)).toDF("a", "b")
val df = Seq((1, 2), (3, 4)).toDF("a", "b")
val df: org.apache.spark.sql.DataFrame = [a: int, b: int]
scala> df.write.mode("overwrite").format("avro").save("avro_file")
df.write.mode("overwrite").format("avro").save("avro_file")
