   > Where is the problem? In Flink? Or in Hive?
   
   For all use case where `HiveCatalog` engaged
   
   1. `HiveCatalog` depends on `org.apache.hadoop.hive.metastore.api`

   2. During the shading phase， all the package pattern 
`org.apache.hadoop.hive` is shaded as 
`org.apache.flink.table.store.shaded.org.apache.hadoop.hive`

   Well for `org.apache.hadoop.hive.metastore.api`, they exists in 
`org.apache.hive:hive-metastore` for Hive2, but is moved to 
`org.apache.hive:hive-standalone-mteastore` for Hive3.
   
   This will cause `NoClassDefFoundError` for  
`org.apache.flink.table.store.shaded.org.apache.hadoop.hive.metastore.api.XXX`
   
   Attach the stacktrace
