我運行在AWS上如下語句引發WARN ReliableDeliverySupervisor：與遠程系統的關聯失敗，地址現在被控制爲[5000] ms。原因：[解除關聯]
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()
可以約2小時運行出現以下錯誤後：

是什麼意思呢？我該如何解決它？
執行人可能跑出內存。因此，您需要檢查丟失的執行程序的容器日誌，並可能檢查其運行的節點上的yarn nodemanager日誌。 – ChristopherB
@ChristopherB thx很多評論！ –
它工作或找到更多的錯誤信息？ – ChristopherB
