Hive3 embedded metastore reports InvalidObjectException(message:No such catalog hive)

Hi, we're maintaining Flink's Hive connector which integrates Hive's meta store as Flink's catalog. But now, we encounter a test issue FLINK-30433 with Hive3.

The exception stack is as follows:

Caused by: InvalidObjectException(message:No such catalog hive) at org.apache.hadoop.hive.metastore.HiveMetaStore$HMSHandler.create_database_core(HiveMetaStore.java:1251) at org.apache.hadoop.hive.metastore.HiveMetaStore$HMSHandler.create_database(HiveMetaStore.java:1325)

We are using embedded metastore for test purpose. I think the hive metastore should have created the default catalog in initialization, ans this exception shoudn't happen. I really can't understand why this happens. Btw, it happens in some times and I can't reproduce it in my local env.

I don't have any clue on it, really appreciated if someone can give some ideas from Hive's side.
