我在 aws spark 上运行以下句子

val sqlContext = new org.apache.spark.sql.SQLContext(sc)
import sqlContext.implicits._

case class Wiki(project: String, title: String, count: Int, byte_size: String)

val data = sc.textFile("s3n://+++/").map(_.split(" ")).filter(_.size ==4 ).map(p => Wiki(p(0), p(1), p(2).trim.toInt, p(3)))

val df = data.toDF()
df.printSchema()

val en_agg_df = df.filter("project = 'en'").select("title","count").groupBy("title").sum().collect()

可以在运行大约 2 小时后得到以下错误:

这意味着什么 ?我该如何解决?

最佳答案

答案似乎已经在评论中提供了:

It seems to be a out-of-memory on executor, because it went well if I add more machine to the cluster
