[jira] [Updated] (SPARK-3284) saveAsParquetFile not working on
windows
[ https://issues.apache.org/jira/browse/SPARK-3284?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Pravesh Jain updated SPARK-3284:
--------------------------------
Description:
{code}
object parquet {
case class Person(name: String, age: Int)
def main(args: Array[String]) {
val sparkConf = new SparkConf().setMaster("local").setAppName("HdfsWordCount")
val sc = new SparkContext(sparkConf)
val sqlContext = new org.apache.spark.sql.SQLContext(sc)
// createSchemaRDD is used to implicitly convert an RDD to a SchemaRDD.
import sqlContext.createSchemaRDD
val people = sc.textFile("C:/Users/pravesh.jain/Desktop/people/people.txt").map(_.split(",")).map(p => Person(p(0), p(1).trim.toInt))
people.saveAsParquetFile("C:/Users/pravesh.jain/Desktop/people/people.parquet")
val parquetFile = sqlContext.parquetFile("C:/Users/pravesh.jain/Desktop/people/people.parquet")
}
}
{code}
gives the error
Exception in thread "main" java.lang.NullPointerException at org.apache.spark.parquet$.main(parquet.scala:16)
which is the line saveAsParquetFile.
This works fine in linux but using in eclipse in windows gives the error.
