Hi ,  
We are trying to index nested documents to elasticsearch using hive . The document that is failing is about 1.5Mb in size and has one parent and about 900 children documents under that . We have applied best practices as per the link below .

[https://www.elastic.co/guide/en/elasticsearch/hadoop/current/hive.html](https://www.elastic.co/guide/en/elasticsearch/hadoop/current/hive.html)

We are loading the document as JSON using string data type .

We are using elasticsearch 1.5 and hive 0.10 .

We keep getting the error as below .
