nevzheng opened a new pull request, #14101:
URL: https://github.com/apache/gravitino/pull/14101

   ### What changes were proposed in this pull request?
   
   - A small `HudiSparkTestUtils` clears Hudi's JVM-wide cached Hive client 
before a test builds its SparkSession; `TestHudiHMSBackendOps` and 
`HudiCatalogHMSIT` call it.
   
   ### Why are the changes needed?
   
   Hudi's `HiveClientUtils` keeps one Hive client per JVM, and it survives 
`SparkSession.close()`. After `TestHudiHMSBackendOps`, it still pointed at that 
test's in-JVM metastore, so `HudiCatalogHMSIT` created its database on the 
container's metastore and its table on the stale one, and failed.
   
   Fix: #14095 (item 6)
   
   ### Does this PR introduce _any_ user-facing change?
   
   No. Test code only.
   
   ### How was this patch tested?
   
   The full `catalog-lakehouse-hudi` module: 18 tests, all pass.
