srowen opened a new pull request #25485: [SPARK-28434][TESTS][ML] Fix values in dummy tree in DecisionTreeSuite URL: https://github.com/apache/spark/pull/25485 ### What changes were proposed in this pull request? Fix dummy tree created in decision tree tests to have actually consistent stats, so that it can be compared in tests more completely. The current one has values for, say, impurity that don't even match internally. With this, the tests can assert more about stats staying correct after load. ### Why are the changes needed? Fixes a TODO and improves the test slightly. ### Does this PR introduce any user-facing change? None ### How was this patch tested? Existing tests.
