The previous filestatus will not be cached, as its source hivetable will be
created every time, and the filestatus will also be created, resulting in
different client IDs for the cached object's key, leading to cache
invalidation. It can cause two problems: 1. Cache failure, which greatly
affects query performance because obtaining filestatus from HDFS is a slow
process.
2. Memory leakage occurs because objects are constantly added to the cache,
and since the default cache time is -1, the memory will become larger and
larger.

<!--
Please clarify why the changes are needed. For instance,
1. If you propose a new API, clarify the use case for a new API.
