Subject [jira] [Commented] (HIVE-16052) MM tables: add exchange partition test after ACID integration
Date Wed, 31 May 2017 23:45:04 GMT

Wei Zheng commented on HIVE-16052:
----------------------------------

exchgpartition2lel.q. When I convert the tables to MM, it produced correct result. Do we want
a counterpart of this test for MM?

> exchgpartition2lel test fails if all tables are changed to MM, because of write ID mismatch
between directories and tables when exchanging partition directories between tables. ACID
should probably fix this because transaction IDs are global.
> We should add a test after integrating with ACID; if it doesn't work for some other reason,
we can either implement it as moving to a new mm_id/txn_id in each affected partition, or
block it on MM tables.
