Github user guoxiaolongzte commented on the issue: https://github.com/apache/spark/pull/20259 Sir, I stick to my point for the following reasons: 1.When the spark system is running for some time, the log has been rolled back, because we use log4j, simply do not see the beginning of the start time. 2.lunix server not everyone has permission to visit, I do not have permission to see, but we are very concerned about the start-up time, we can only see the WEB UI. 3. It's already crowded. I can adjust the details, look at the snapshot, what do you think? ![2](https://user-images.githubusercontent.com/26266482/34925730-1781348c-f9e6-11e7-9ef0-ad84fff03f04.png)
