I think it can target for 3.0. since 2.4 will be released soon and this PR 
looks a little complex and need take  some time to check carefully.

as @WeichenXu123 mentioned in 
https://github.com/apache/spark/pull/22764#discussion_r228527916, I don't see 
other problems with the current PR. The only thing is: do we want to target it 
for 2.4 or for 3.0? If the latter, I'll update the PR with the proper 
deprecation messages. Thanks.

Github user cloud-fan commented on the issue:

Since this PR is a little more complicated than we expect, we decided to 
not have it in 2.4.0. I'm not sure if we can treat it as a special case and put 
it in 2.4.1, cc @mengxr 

Anyway, the other 2 related PRs(deprecating the API and updating the 
example) are reverted. We need to think about what we should do if we can only 
do this in 3.0.

2018-10-18 Thread mgaido91
Github user mgaido91 commented on the issue:

https://github.com/apache/spark/pull/22764
  
For KMeans we used the ClusteringEvaluator in the examples. Actually, the 
training cost is not a good way to evaluate a dataset (the evaluation should be 
done on a dataset different from the training one).

Maybe we can also add this API in the example to show that it exists, but I 
have seen no example with a summary shown so...
