   @JackieTien97 I replayed this test case `IoTDBUDTFAlignByTimeQueryIT.queryWithValueFilter9` in a cluster with 3 nodes and 2 replicas. It can reappear in 100%. This is the debug screenshot. I guess the reason is that although the `cachedTimeCnt` is not empty, there's no data matched the `cachedTimeCnt` and a null result returns. This only happens in cluster query.
