Remus Rusanu reassigned HIVE-16438: ----------------------------------- > Support inclusive sort order on ReduceDink deduplication > -------------------------------------------------------- > > Key: HIVE-16438 > URL: https://issues.apache.org/jira/browse/HIVE-16438 > Project: Hive > Issue Type: Bug > Components: Query Planning > Reporter: Remus Rusanu > Assignee: Remus Rusanu > > HIVE-11132, HIVE-12664 and HIVE-15708 hit issues around the > ReduceSinkDeDuplicate logic. The patch for HIVE-15708 forces the sort order > of all reduced operators to be the same, disallowing for allowance of less > restrictive sort in parent RS operators that are covered by the more > restrictive child RS operator. Logically this condition should be allowed, > ie. child operator sorts by {{(A, B, C)}} and parent sorts by {{(A,B)}} it > should be merged. This is the JIRA to track that work. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
