> Disable conversion of managed table to external and vice versa at source.
> -------------------------------------------------------------------------
>
> Key: HIVE-21500
> URL: https://issues.apache.org/jira/browse/HIVE-21500
> Project: Hive
> Issue Type: Sub-task
> Affects Versions: 4.0.0
> Reporter: Sankar Hariappan
> Assignee: Sankar Hariappan
> Priority: Major
> Labels: DR, Replication, pull-request-available
> Attachments: HIVE-21500.01.patch, HIVE-21500.02.patch
>
> Time Spent: 10m
> Remaining Estimate: 0h
>
> Couple of scenarios for Hive2 to Hive3(strict managed tables enabled)
> replication where managed table is converted to external at source.
> *Scenario-1: (ACID/MM table converted to external at target)*
> 1. Create non-ACID ORC format table.
> 2. Insert some rows
> 3. Replicate this create event which creates ACID table at target (due to
> migration rule). Each insert event adds transactional metadata in HMS
> corresponding to the current table.
> 4. Convert table to external table using ALTER command at source.
> *Scenario-2: (External table at target changes table location)*
> 1. Create non-ACID avro format table.
> 2. Insert some rows
> 3. Replicate this create event which creates external table at target (due to
> migration rule). The data path is chosen under default external warehouse
> directory.
> 4. Convert table to external table using ALTER command at source.
> It is unable to convert an ACID table to external table at target. Also, it
> is hard to detect what would be the table type at target when perform this
> ALTER table operation at source.
> So, it is decided to disable conversion of managed table at source (Hive2) to
> EXTERNAL or vice-versa if the DB is enabled for replication and strict
> managed is disabled.
