> Now in ExecutionGraphHolder, which is used in many handlers, we use a WeakHashMap to cache ExecutionGraph(s), which is only sensitive to garbage collection.
> The latency is too high when JVM do GC rarely, which will make status of jobs or its tasks unmatched with the real ones.
> LoadingCache is a common used cache implementation from guava lib, we can use its time based eviction to lower latency of status update.
