Thomas D'Silva updated PHOENIX-4568: ------------------------------------ Fix Version/s: (was: 4.15.0) > Duplicate entries in the GroupBy structure when running > AggregateIT.testTrimDistinct > ------------------------------------------------------------------------------------ > > Key: PHOENIX-4568 > URL: https://issues.apache.org/jira/browse/PHOENIX-4568 > Project: Phoenix > Issue Type: Bug > Affects Versions: 4.12.0 > Environment: minicluster > Reporter: Csaba Skrabak > Assignee: Csaba Skrabak > Priority: Minor > > AggregateIT.testTrimDistinct case is introduced in the fix of PHOENIX-4139. > Trace-debugging the test reveals that the GroupBy class may store duplicates > of accessor objects in its list fields, keyExpressions and expressions. > "Since the second trim expression is the same a the first one, the group by > (district turns into a group by) of the second one should be ignored as it > serves no purpose. That is what occurs when you do a select without the > distinct. Perhaps this logic is missing from GroupByCompiler?" > https://issues.apache.org/jira/browse/PHOENIX-4139?focusedCommentId=16274531&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-16274531 > I have not yet found any test case in which this internal behavior would > cause an error but still. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
