> Key: HIVE-18748
> URL: https://issues.apache.org/jira/browse/HIVE-18748
> Project: Hive
> Issue Type: Sub-task
> Components: HiveServer2, Transactions
> Affects Versions: 3.0.0
> Reporter: Sankar Hariappan
> Assignee: Sankar Hariappan
> Priority: Major
> Labels: ACID, DDL
> Fix For: 3.1.0
>
>
> ACID implementation uses metatables such as TXN_COMPONENTS,
> COMPLETED_TXN_COMPONENTS, COMPACTION_QUEUE, COMPLETED_COMPCTION_QUEUE etc to
> manage ACID operations.
> Per table write ID implementation (HIVE-18192) introduces couple of
> metatables such as NEXT_WRITE_ID and TXN_TO_WRITE_ID to manage write ids
> allocated per table.
> Now, when we rename any tables, it is necessary to update the corresponding
> table names in these metatables as well. Otherwise, ACID table operations
> won't work properly.
> Since, this change is significant and have other side-effects, we propose to
> disable rename tables on ACID tables until a fix is figured out.
