未在AWS EMR中找到SPARK_CONF

Question

我正試圖在EMR中部署一個Spark應用程序，並面臨以下問題。

java.io.FileNotFoundException: File does not exist: hdfs://ip-10-184-176-172.ec2.internal:8020/user/hadoop/.sparkStaging/application_1446113189622_0004/__spark_conf__2712437380309904293.zip

我正在使用emr控制檯UI以集羣模式進行部署。在第一行中，它指定SPARK_CONF壓縮文件被上載到hdfs位置，但錯誤說在同一位置找不到文件。有沒有人遇到類似的問題？

已解決問題。我使用的是不受支持的JAVA版本。 EMR有java 7，我的應用程序是用java 8開發的。
