Change subject: IMPALA-12737: Refactor the Workload Management Initialization Process. ...................................................................... Patch Set 13: (1 comment) http://gerrit.cloudera.org:8080/#/c/21653/11/be/src/service/workload-management-init.cc File be/src/service/workload-management-init.cc: http://gerrit.cloudera.org:8080/#/c/21653/11/be/src/service/workload-management-init.cc@193 PS11, Line 193: /// Aborts with error if the target_ver is less than the actual_ver. > I dug into the code more, and adding support for downgrades is not a trivia I'd outlined a set of upgrade tests that I think will need that support. That seems to mean workload_mgmt_schema_version is pointless as a parameter, you can't actually change it's value at runtime; it will set up an older version of the table, then try to insert columns that don't exist. So what we currently support is: 1. Impala can run against a table that is newer than its latest known version 2. you can't configure Impala to run with an older version than the latest it supports -- To view, visit http://gerrit.cloudera.org:8080/21653 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-Project: Impala-ASF Gerrit-Branch: master Gerrit-MessageType: comment Gerrit-Change-Id: Id645f94c8da73b91c13a23d7ac0ea026425f0f96 Gerrit-Change-Number: 21653 Gerrit-PatchSet: 13 Gerrit-Owner: Jason Fehr <[email protected]> Gerrit-Reviewer: Impala Public Jenkins <[email protected]> Gerrit-Reviewer: Jason Fehr <[email protected]> Gerrit-Reviewer: Michael Smith <[email protected]> Gerrit-Reviewer: Riza Suminto <[email protected]> Gerrit-Comment-Date: Thu, 22 Aug 2024 20:03:52 +0000 Gerrit-HasComments: Yes
