Subject [jira] [Commented] (HIVE-21254) Pre-upgrade tool should handle exceptions and skip db/tables
Date Wed, 13 Feb 2019 19:57:00 GMT

    [ https://issues.apache.org/jira/browse/HIVE-21254?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16767537#comment-16767537

Prasanth Jayachandran commented on HIVE-21254:
----------------------------------------------

Also how does compactor know the table user if it cannot do getTable() to get location and
find user? getTable() throws ACL exception if hive user does not have read access to end user
location.

> 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.
