>
> Some of the events from Hive2 may cause conflicts in Hive3
> (hive.strict.managed.tables=true) when applied. So, need to handle them
> properly.
> 1. Alter table to convert non-acid to acid.
> - This event should be no-op as the table in target might be already acid or
> MM or external table.
> 2. Alter table or partition that changes the location.
> - For managed tables at source, the table location shouldn't be changed for
> the given non-partitioned table and partition location shouldn't be changed
> for partitioned table as alter event doesn't capture the new files list. So,
> it may cause data inconsistsency. So, if database is enabled for replication
> at source, then alter location on managed tables should be blocked.
> - For external tables, if location is changed at source, then location should
> be updated only for the given object (table or partition, not all partitions).
