William Montaz 25f506e2ad [SPARK-25973][CORE] Spark History Main page performance improvement ... HistoryPage.scala counts applications (with a predicate depending on if it is displaying incomplete or complete applications) to check if it must display the dataTable. Since it only checks if allAppsSize > 0, we could use exists method on the iterator. This way we stop iterating at the first occurence found. Such a change has been relevant (roughly 12s improvement on page loading) on our cluster that runs tens of thousands of jobs per day. Closes #22982 from Willymontaz/SPARK-25973.
