我們有一個運行在AWS Elastic MapReduce（EMR）和Spark 1.6.1中的Hadoop集羣。沒有任何問題在羣集主機上提交併提交Spark作業，但我們希望能夠從另一個獨立的EC2實例提交它們。從EMR集羣主節點使用spark-submission外部
其他「外部」EC2實例具有安全組設置，以允許所有來往於EMR實例主節點的TCP流量和來自其實例的TCP流量。它具有從Apache網站直接下載的Spark二進制安裝。
複製了的/ etc/Hadoop的/ conf文件夾從主到這個實例，並相應設置$ HADOOP_CONF_DIR，當試圖提交的SparkPi例子，我碰到以下權限問題：

它如果使用集羣部署模式進行提交，則不會有任何區別。有問題的用戶是在外部EC2實例（我們有多個開發人員帳戶）上的本地用戶，該用戶在羣集的主節點或從節點上不存在（甚至在本地，用戶主目錄位於/ home，而不是/用戶）。
我不知道發生了什麼。任何幫助不勝感激。
更新：如果我創建本地「hadoop」用戶並以該用戶的身份運行spark-submit或pyspark，它確實會按預期工作，但這不是我們想要的。 – DavidJ
