Lars Volker created IMPALA-6756: ----------------------------------- Summary: Order children of profiles in a canonical way Key: IMPALA-6756 URL: https://issues.apache.org/jira/browse/IMPALA-6756 Project: IMPALA Issue Type: Improvement Components: Backend Affects Versions: Impala 2.12.0 Reporter: Lars Volker
IMPALA-6694 addressed an issue where variations in the execution order across multiple backends changed the order of a fragment instance's profile children. Instead of relying on the order in which children are created on the worker nodes and reported to the coordinator, we should introduce a canonical order, e.g. have the non-exec-node children appear before the exec-nodes, and order them alphabetically.
