ASF GitHub Bot commented on FLINK-2030: --------------------------------------- Github user sachingoel0101 commented on the pull request: https://github.com/apache/flink/pull/861#issuecomment-137763865 1. @thvasilo , I have changed the scala `DataSetUtils` class to make it a bit more easy to use. Now, it doesn't require an import of `org.apache.flink.api.scala.DataSetUtils.utilsToDataSet`, rather a more intuitive `org.apache.flink.api.scala.DataSetUtils._`. Lemme know if this is a good fix to have it along with this PR. https://gist.github.com/sachingoel0101/987ebb7cbfacb793d610 2. I will write the docs for the Utility part. 3. Right now, I have duplicated the implementation from `DataSetUtils.java` directly to `DataSetUtils.scala`. If you find a way to directly access a scala `DataSet[Double]` from java, let me know. :) > Implement discrete and continuous histograms > -------------------------------------------- > > Key: FLINK-2030 > URL: https://issues.apache.org/jira/browse/FLINK-2030 > Project: Flink > Issue Type: Sub-task > Components: Core > Reporter: Sachin Goel > Assignee: Sachin Goel > Priority: Minor > > For the implementation of the decision tree in > https://issues.apache.org/jira/browse/FLINK-1727, we need to implement an > histogram with online updates, merging and equalization features.
