Description

Recently, we hit this issue when testing spark2.3. It report the following error messages when clicking on the stage UI link.

We add more logs to print the executorId(here is 10) to debug, and finally find out that it's caused by the inconsistency between the list of `ExecutorStageSummaryWrapper` and the `ExecutorSummaryWrapper` in the KVStore. The number of deadExecutors may exceeded threshold and being removed from list of `ExecutorSummaryWrapper`, however, it may still be kept in the list of `ExecutorStageSummaryWrapper` in the store.
