The fix LGTM. If a table has only one bucket, it can satisfy `AllTuples` and no shuffle is needed for aggregate without group keys. However, if we disable bucket scan, then `AllTuples` is not satisfied any more and the query returns wrong result. @IonutBoicuAms can you open a JIRA ticket and also enrich the PR description a little bit to explain why the bug happens? -- This is an automated message from the Apache Git Service.
