Change subject: IMPALA-8831: Support ALTER TABLE RENAME for insert_only ACID tables ...................................................................... IMPALA-8831: Support ALTER TABLE RENAME for insert_only ACID tables ALTER TABLE commands were not allowed on ACID tables until now. This patch enables most ALTER TABLE statements for insert only tables. Generally ACID tables can be altered the same way as non-ACID tables, just an exclusive table lock needs to acquired before calling alter_table on HMS. There are a few exceptions: - ALTER TABLE SET TBLPROPERTIES and ADD PARTITION need only shared locks. - Stats related operations open a transaction currently and are handled separately. - ALTER TABLE RECOVER PARTITIONS makes no sense for ACID tables. - ALTER TABLE RENAME TO turned out to be more complicated, as HMS needs transactional information to migrate stats during rename. A follow up Jira is created to support rename: IMPALA-9031. Some .test files were split to parts based on whether it is possible to run those queries on ACID tables. As a result .test changes are nearly all copy paste.
