Error saving Spark RDD using rdd.saveToEs

Elastic Stack Elasticsearch
1

I have a simple Spark data frame which contains a column of JSON strings. When I run the following code:

import org.elasticsearch.spark._
val df = Seq("""{"name": "john", "age":44}""").toDF("json")
df.rdd.map(x=>x.getAs[String]("json")).saveToEs("test-index-df/post")

I get the error below:

17/08/13 21:51:58 ERROR TaskContextImpl: Error in TaskCompletionListener

Anyone have any idea what I am doing wrong?

I would make sure that the JSON you are saving does not contain any non printing characters or unicode characters in standard json token locations (Like special quote characters)
