             Summary: [C++] Spurious test failure in ScanNode.MinimalGroupedAggEndToEnd
                 Key: ARROW-14040
                 URL: https://issues.apache.org/jira/browse/ARROW-14040
             Project: Apache Arrow
          Issue Type: Bug
          Components: C++
            Reporter: David Li
             Fix For: 6.0.0


[https://github.com/ursacomputing/crossbow/runs/3648596923]

The test assumes a certain order, but there is no guarantee of output order. (We should probably locally run these tests with constrained resources to try to stress them and find other instances of this assumption.)
