> According to Hive documentation, MetaStorePreEventListener should be used to perform authorization and/or additional actions for every metastore call. MetaStorePreEventListener is implemented and works for some calls, but does not work for others. For example, It does work for calls: getTable, createDatabase, createTable, alterTable, alterPartition, etc... but does not get called for alterDatabase, getFields, getDatabases, getTableStatistics, etc...
> Proper implementation of MetaStorePreEventListener would require a lot of changes in different classes so it seems that it is better to add a similar listener in the descendant of org.apache.thrift.ProcessFunction and change ThriftHiveMetastore generated by thrift compiler to descend all auto-generated classes from it, not from the  ProcessFunction directly. This applies to all versions of HiveMetastore with  MetaStorePreEventListener implemented. 
> I would like to contribute code for this functionality for the trunk - please let me know your suggestions and thoughts.
> Thanks!
