Hi,  
I try to insert parent doc to specific type, and child doc to another type in the same spark job.  
I defined in the spark conf the es.mapping.parent to the correct field.  
But when the job tries to saveJsonToEs(\<INDEX/TYPE\_NAME\>) , I got this exception:  
Caused by: org.elasticsearch.hadoop.EsHadoopIllegalArgumentException:[JsonExtractor for field [parent]] cannot extract value from entity [class java.lang.String]

Thank's,

I found the solution:  
In the saveJsonToEs(\<INDEX\_NAME/TYPE\_NAME\>, Map("es.mapping.parent" -\> \<NAME\_OF\_PARENT\_FILED\> ))  
Instead of, defining it in the conf object of spark.

Both configurations should work - what version of ES-Hadoop are you using and how do you define the `es.mapping.parent` "in the conf object of spark." ?
