KMeansModel.KMeansParameter does not has a member '_estimate_k'

Language : Scala 2.10

Hi. I'm using a sparkling water with scala.
I tried KMeans and met an error.

--
$spark-shell --master yarn-client --jars "sparkling-water-1.6.8/assembly/build/libs/sparkling-water-assembly-1.6.8-all.jar"
scala>import root.hex.kmeans.KMeansModel.KMeansParameter
scala>val param = new KMeansParameter
scala>param._estimate_k
error:value _estimate_k is not a member of hex.kmeans.KMeansModel.KMeansParameters

Any other parameters are OK e.g. _k, _max_iterations,etc

Maybe, the '_estimate_k' is defined in the below code.

How can I use '_estimate_k'?

@YMorisawa Sparkling Water 1.6.x is using an older H2O version, which doesn't support this parameter yet that's why it's not there.

You can try our latest Sparkling Water 2.x branch, otherwise you'd have to wait for the next 1.6.x release.
