### What changes were proposed in this pull request? It turns out bumping to 10 seconds even 20 seconds still doesn't work - https://github.com/apache/gravitino/pull/8870. It's because Caffeine's W-TinyLFU eviction algorithm is **NON-DETERMINISTIC**. It doesn't guarantee which specific entries will be evicted, even after an hour. It makes probabilistic decisions based on: - Access frequency (how often accessed) - Recency (when last accessed) - Random sampling for efficiency - Weight of entries Although weight plays a significant role, it's not the sole indicator on which cache to evict. With the change in this PR: 1. We checks some tags were evicted, instead of all checking all tag caches are evicted. This verifies that with the weight, at least some tag caches will be evicted. ### Why are the changes needed? Fix the flaky test of testPolicyAndTagCacheWeigher Fix: [#8861](https://github.com/apache/gravitino/issues/8861) ### Does this PR introduce _any_ user-facing change? No ### How was this patch tested?
