Hi,

I'm working for Couchbase on the Couchbase Spark Connector and noticed something weird which I haven't been able to get to the bottom of so far.

For query DataFrames we use the Datasource v2 API and we delegate the JSON parsing to the org.apache.spark.sql.catalyst.json.CreateJacksonParser -- (https://github.com/couchbase/couchbase-spark-connector/blob/master/src/main/scala/com/couchbase/spark/query/QueryPartitionReader.scala#L56) .. this all works fine, both in a local IDE setup or when the job is sent to a local spark distributed setup.

But when I run it in a databricks notebook, I get:

Job aborted due to stage failure.
Caused by: NoSuchMethodError: org.apache.spark.sql.catalyst.json.CreateJacksonParser$.string(Lcom/fasterxml/jackson/core/JsonFactory;Ljava/lang/String;)Lcom/fasterxml/jackson/core/JsonParser;

Any idea why Caused by: NoSuchMethodError: org.apache.spark.sql.catalyst.json.CreateJacksonParser$.string(Lcom/fasterxml/jackson/core/JsonFactory;Ljava/lang/String;)Lcom/fasterxml/jackson/core/JsonParser; is not available in this environment?

Thanks,
