Change subject: IMPALA-4063: Merge report of query fragment instances per executor ...................................................................... Patch Set 5: (2 comments) http://gerrit.cloudera.org:8080/#/c/11615/5//COMMIT_MSG Commit Message: http://gerrit.cloudera.org:8080/#/c/11615/5//COMMIT_MSG@14 PS5, Line 14: In addition, due to the lack of coordination between query : fragment instances, a query may end without collecting the profiles : from all fragment instances when one of them hits an error before : another fragment instance manages to finish Prepare(), leading to : missing profiles for certain fragment instances. Does this mean that we've fixed the problem in IMPALA-7148 and can re-enable those tests? In particular, are we now guaranteed that in a query that completes successfully but has some fragments cancelled internally (eg. because of a LIMIT) the coordinator will receive and apply at least one profile from every fragment instance? http://gerrit.cloudera.org:8080/#/c/11615/5/testdata/workloads/functional-query/queries/QueryTest/udf-non-deterministic.test File testdata/workloads/functional-query/queries/QueryTest/udf-non-deterministic.test: http://gerrit.cloudera.org:8080/#/c/11615/5/testdata/workloads/functional-query/queries/QueryTest/udf-non-deterministic.test@18 PS5, Line 18: ---- QUERY This test doesn't really have anything to do with nondeterminism.
