> There's some code in original txn stats patch that may go to metastore to get write Ids. This code should not go to metastore, it should fail instead. 
> HIVE-19382 should ensure that we have correct IDs already present during optimizer - they are using by e.g. materialized view optimizer, so they should be there; if they are not present, some integration might be needed so that txn stats optimizations also have access to those write Ids.
