> The job page will be too slow to open when there are thousands of executor events(added or removed). I found that in ExecutorsTab file, executorIdToData will not remove elements, it will increase all the time. Before this pr, it looks like timeline1.png. After this pr, it looks like timeline2.png(we can set how many events will be displayed)
