Link: https://github.com/databricks/spark-corenlp I have downloaded the jar for the above wrapper from here and also downloaded Stanford NLP jars from here. Then I have added both sets of jars as dependencies in Spark2 interpreter settings of Zeppelin and restarted the interpreter. Still the below sample program gives the error
