Matt McCline updated HIVE-19116: -------------------------------- Attachment: HIVE-19116.01.patch > Vectorization: Vector Map data type doesn't keep the order of the key/values > pairs as read > ------------------------------------------------------------------------------------------ > > Key: HIVE-19116 > URL: https://issues.apache.org/jira/browse/HIVE-19116 > Project: Hive > Issue Type: Bug > Components: Hive > Affects Versions: 3.0.0 > Reporter: Matt McCline > Assignee: Matt McCline > Priority: Critical > Attachments: HIVE-19116.01.patch > > > The VectorExtractRow class does not preserve the order of the key/value pairs > when going from MapColumnVector to a Map object. This causes Q file > differences in tests with the MAP data type making it seem like we are > getting Wrong Results (well, actually we are). > When LazyMap class (for example) adds key/value pairs to its "map" it uses a > LinkedHashSet to preserve insert order. > FYI: [~teddy.choi] -- This message was sent by Atlassian JIRA (v7.6.3#76005)
