> Hi,
>  
> I am using Databricks cluster with configuration as Spark: 3.0.0 and Scala: 2.12 and want to create Machine Learning pipelines using MLeap - latest version: 0.16.1.
> In my pipeline, I have created ensemble model. I am to serialize the model to a bundle.
> But the issue comes while deserializing it. Below is the error I am facing:
> _java.lang.NoSuchMethodError: org.apache.spark.mllib.tree.impurity.ImpurityCalculator$.getCalculator(Ljava/lang/String;[D)Lorg/apache/spark/mllib/tree/impurity/ImpurityCalculator;_
>  
> I tried using another cluster with the configuration as - spark: 2.4.5, scala: 2.11 and MLeap: 0.16.0. There it is working fine.
> Please suggest.
