Looking at https://issues.apache.org/jira/browse/HIVE-9350 (Add ability for HiveAuthorizer implementations to filter out results of 'show tables', 'show databases') I see that it changed methods of MetaStoreFilterHook to throw exceptions which id didn't throw before. This means that any clients using it require recompilation (and potential code changes to handle exceptions) which is a compatibility issue. This was done in 1.2.0 - IN am wondering how such compatibility issues were handled in Hive 1 and Hive 2 branches?
Thanks for clarification, - Alex
