我正在使用spark將大文件寫入HDFS。基本上我所做的就是加入3個大文件，然後使用toJSON（）將結果數據框轉換爲json，然後使用saveAsTextFile將其保存到HDFS。最後寫的文件大約是4TB。應用程序運行速度非常慢（正如我應該預料的那樣），6小時後它會拋出異常java.lang.IllegalArgumentException：不允許自我抑制。詳細的失敗原因是從監控頁面複製到以下：Spark：將大文件寫入HDFS時不允許自我抑制

誰能告訴我是什麼原因導致這個問題，我該如何解決它？
看起來像你的HDFS的一個問題： 產生的原因：org.apache.hadoop.ipc.RemoteException（java.io.IOException異常）：文件/用戶/大魏/ upid_json_all/_temporary/0/_temporary/attempt_201512210857_0006_m_000037_361/part-00037只能複製到0節點而不是minReplication（= 1）。有5個數據節點正在運行，並且此操作中不包含任何節點。 檢查您的ulimit並在DFS日誌中查看正在發生的事情。 – AkhlD
你在使用eclipse嗎？ –
Nah，pycharm上的python。我想這可能是由於磁盤空間不足 - 我的磁盤上只剩下大約7TB，不足以進行3次重複。 – TheStupidOne
