Subject [jira] [Commented] (HIVE-21254) Pre-upgrade tool should handle exceptions and skip db/tables
Date Wed, 13 Feb 2019 20:53:00 GMT


Prasanth Jayachandran commented on HIVE-21254:

Yup. Just discussed with [~ashutoshc] about the same. Detect ACL Exception and explicitly
throw with property to allow read access and retry. Will update the patch.

> When exceptions like AccessControlException is thrown, pre-upgrade tool fails. If hive
user does not have read access to database or tables (some external tables denies read access
to hive), pre-upgrade tool should just assume they are external tables and move on without
failing pre-upgrade process.
