推荐答案

我在Google Cloud Dataproc上使用Spark时遇到了同样的问题.

I have faced the same issue while using Spark on Google Cloud Dataproc.

如果您不是直接通过4040端口而是通过YARN Web UI(8088端口)访问Spark Job UI，您将看到正确呈现的网页.

If you will access Spark Job UI not through 4040 port directly, but through YARN Web UI (8088 port) you will see correctly rendered web pages.

要解决此问题，直接通过4040端口直接访问Spark UI时，您需要重置Spark作业内的spark.ui.proxyBase属性(不在CLI/job提交命令中)，因为它会被Spark UI代理覆盖:

To workaround this issue when accessing Spark UI directly through 4040 port you need to reset spark.ui.proxyBase property inside your Spark job (not in CLI/job submission command), because it gets overridden by Spark UI proxy:

sys.props.update("spark.ui.proxyBase", "")

这是此问题的详细说明.
