> I'm trying to update a nested field using Spark and a scripted update. The code I'm using is:
> update_params = "new_samples: samples"
>  update_script = "ctx._source.samples += new_samples"
> es_conf = {
>  "es.mapping.id": "id",
>  "es.mapping.exclude": "id",
>  "es.write.operation": "upsert",
>  "es.update.script.params": update_params,
>  "es.update.script.inline": update_script
>  }
> result.write.format("org.elasticsearch.spark.sql").options(**es_conf).option("es.nodes",configuration["elasticsearch"]["host"]).option("es.port",configuration["elasticsearch"]["port"] ).save(configuration["elasticsearch"]["index_name"]+"/"+configuration["version"],mode='append')
> And the schema of the field is:
> |-- samples: array (nullable = true)
>  | |-- element: struct (containsNull = true)
>  | | |-- gq: integer (nullable = true)
>  | | |-- dp: integer (nullable = true)
>  | | |-- gt: string (nullable = true)
>  | | |-- adBug: array (nullable = true)
>  | | | |-- element: integer (containsNull = true)
>  | | |-- ad: double (nullable = true)
>  | | |-- sample: string (nullable = true)
> And I get the following error:
> py4j.protocol.Py4JJavaError: An error occurred while calling o83.save.
>  : org.apache.spark.SparkException: Job aborted due to stage failure: Task 0 in stage 1.0 failed 1 times, most recent failure: Lost task 0.0 in stage 1.0 (TID 1, localhost, executor driver): java.lang.ClassCastException: scala.collection.mutable.WrappedArray$ofRef cannot be cast to scala.Tuple2
> Am I doing something wrong or is this a bug? Thanks.
