huaxingao opened a new pull request #28786: URL: https://github.com/apache/spark/pull/28786
### What changes were proposed in this pull request? In LogisticRegression and LinearRegression, if set maxIter=n, the model.summary.totalIterations returns n+1 if the training procedure does not drop out. This is because we use ```objectiveHistory.length``` as totalIterations, but ```objectiveHistory``` contains init sate, thus ```objectiveHistory.length``` is 1 larger than number of training iterations. ### Why are the changes needed? correctness ### Does this PR introduce _any_ user-facing change? No ### How was this patch tested? add new tests and also modify existing tests ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
