纱线应用程序已接受但尽管分配了资源仍未运行cloudera

Question

我正在使用Cloudera quickstart VM 5.13.0.0在yarn-client模式下运行Spark应用程序。我已经为我的Cloudera VM分配了10GB和3个内核。当我提交应用程序时，该应用程序已被接受，但从未进入运行状态。当我尝试使用yarn logs -applicationId查找日志时，我什么也看不到。它绝对是空白。

我在以下位置查找了此问题：

我几乎已经干预了这些链接遇到问题的所有配置。我的问题仍然没有答案，从表面上看，它看起来像上面链接中的问题。这是我的cloudera集群的配置参数：

这是当应用程序仍处于ACCEPTED状态时，队列描述的样子：

同样，这是来自Yarn RM UI的记录（注意，已分配资源（内存/ cpu，并且正在运行的容器显示了一个正在运行的容器]）：

这里是应用程序摘要：

以下是应用程序日志（空）：

最后，这是驾驶员看到的：

可以解决此问题吗？

Answer 1

经过全部研究，除了我在问题中提到的链接中提到的原因之外，我发现这可能由于各种原因而发生：

1. 当客户端（驱动程序）和集群中具有不同版本的spark时。一旦确保两者捆绑了相同版本的spark，它就可以正常运行。
2. 您可能需要提及属性spark.driver.host。确保可以从来宾VM ping通此处传递的IP。
