Is it Live UI or History UI? Also could you please check if any event drops happened or not?

> The number of active tasks is negative in UI Executors page when there is executor lost and task failure. I am using spark on yarn which built on AWS spot instances. When yarn work lost, there is a large probability to become negative active tasks in Spark UI.  
> I saw related tickets below and resolved in earlier version of Spark. But Same things happened again in Spark 2.4.1. See attachment.
