我尝试从 s3 存储桶读取数据并在 Spark 中进行计算并将输出写入 s3 存储桶。此过程已成功完成。但是，在 EMR 步骤级别，我看到作业失败。如果我看到日志，它显示文件不存在。
请参阅下面的日志。

我可以看到我的预期输出结果，但作业显示它失败了。 我错过了什么吗？
这是我的代码：
package Spark_package
import org.apache.spark.SparkConf
import org.apache.spark.sql.SparkSession
object SampleFile {
def main(args: Array[String]) {
val spark = SparkSession.builder.master("local[*]").appName("SampleFile").getOrCreate()
val sc = spark.sparkContext
val conf = new SparkConf().setAppName("SampleFile")
val sqlContext = spark.sqlContext
val df = spark.read.format("csv").option("header","true").option("inferSchema","true").load("s3a://test-system/Checktool/Zipdata/*.gz")
df.createOrReplaceTempView("data")
val res = spark.sql("select count(*) from data")
res.coalesce(1).write.format("csv").option("header","true").mode("Overwrite").save("s3a://dev-system/Checktool/bkup/")
spark.stop()
}
}
请帮我如何解决这个问题？
删除 master（local[*]） 并在相应的集群上运行它。
