I am facing a similar issue. I am able to read from a salesforce table but unable to write to it. Our databricks has also been whitelisted in Salesforce. I am using the same library - "com.springml.spark.salesforce".

The error I am getting is not the same but quite similar -

Error writing to Salesforce: An error occurred while calling o3894.save.
: org.apache.spark.SparkException: Job aborted due to stage failure: Task 0 in stage 77.0 failed 4 times, most recent failure: Lost task 0.3 in stage 77.0 (TID 301) (10.42.102.202 executor 4): java.lang.NoSuchMethodError: com.fasterxml.jackson.databind.DeserializationContext.handleSecondaryContextualization(Lcom/fasterxml/jackson/databind/JsonDeserializer;Lcom/fasterxml/jackson/databind/BeanProperty;)Lcom/fasterxml/jackson/databind/JsonDeserializer;

Any resolution on this will be helpful.
