> Hello!
> 1. I encounter a similar issue (see below text) on Pyspark 2.2 (e.g., dataframe with
~50000 rows x 1100+ columns as input to ".fit()" method of CrossValidator() that includes
Pipeline() that includes StringIndexer(), VectorAssembler() and DecisionTreeClassifier()).
> 2. Was the aforementioned patch (aka fix(https://github.com/apache/spark/pull/15480)
not included in the latest release; what are the reason and (source) of and solution to this
persistent issue please?
> py4j.protocol.Py4JJavaError: An error occurred while calling o9396.fit.
