我正在運行EMR 5.0羣集，我正在使用HUE創建OOZIE工作流程來提交SPARK 2.0作業。我已經直接在YARN上提交了一個spark-submit作業，並作爲同一個集羣上的一個步驟。沒問題。但是，當我與HUE做到這一點，我得到以下錯誤：無法在EMR 5.0上實例化SparkSession HUE

當我沒有在我的星火作業中使用spark.sql或SparkSession（而不是我用SparkContext）運行良好。如果有人有任何線索，我將非常感激。

它與你如何建立你的胖罐有關。 JettyUtils無法從靜態包org/apache/spark/sql/execution/ui/static中檢索文件。你能提供你的Maven程序集插件代碼嗎？ – RudyVerboven
