如何以編程方式在yarn-client模式下提交spark應用程序？

Question

我有一個簡單的spark工作，它用給定的輸入文件中的逗號替換空格。

當本地提交此作業時（使用IDE並執行內置的jar），它會成功完成，並且當主設備設置爲「yarn-client」時，作業會掛起很長時間，並引發以下異常。

我們有一個用例，我們希望以編程方式提交工作，而不是通過構建jar並通過spark-submit提交它。

星火版本：1.6.1 的Hadoop版本：2.7.1

和我在我的POM所有的火花，紗和Hadoop的依賴。

工作失敗，原因是以下異常

我不得不添加hadoop和yarn配置，以成功提交yarn-client模式下的應用程序。

您不能遠程提交您的火花的工作在客戶端模式，因爲您的計算機必須運行需要大量連接的驅動程序本身。如果您堅持使用此方法，則必須配置防火牆以允許某個端口連接到羣集。使用集羣模式或從主節點提交它不那麼痛苦。
