> The issue is similar to, the final phenomenon of the issue is the same,
> because the parameter encode twice
> https://issues.apache.org/jira/browse/SPARK-32467
> https://issues.apache.org/jira/browse/SPARK-33611
> The two issues solve two scenarios to avoid encode twice:
> 1. https redirect proxy
> 2. set reverse proxy enabled (spark.ui.reverseProxy) in Nginx
> But if encode twice due to other reasons, such as this issue (yarn proxy), it
> will also fail
