我已经在intellij IDE中使用spark 1.6.0在scala中编写了一个小程序,jar生成了,但是在运行时抛出错误。
请分享您的意见以解决此问题。
[cloudera@quickstart ~]$ spark-submit --master local --class com.sample.sample.sample /home/cloudera/Desktop/IdeaProjects.jar

I have tried options provided in existed thread like delete MANIFEST.MF file..etc , But no luck
package com.sample.sample
import org.apache.spark.sql.SQLContext
import org.apache.spark.{SparkConf, SparkContext}
object sample {
def main(args: Array[String]): Unit = {
println("Hello World")
val conf = new SparkConf().setAppName("JDBC App").setMaster("local")
val sc = new SparkContext(conf)
// val sc = new SparkConf()
val sqlContext = new SQLContext(sc)
val url ="jdbc:mysql://localhost:3306/retail_db?user=root&password=cloudera"
val df = sqlContext.read.format("jdbc").option("url", url).option("dbtable", "products").load()
df.printSchema()
}
}
以下是我正在运行的命令:
spark-submit --master local --class com.sample.sample.sample /home/cloudera/Desktop/IdeaProjects.jar
expecting this code should work
