hi
This is a document about es for hadoop's coniguration.
https://www.elastic.co/guide/en/elasticsearch/hadoop/current/configuration.html
It only tells me that property 'es.read.field.include' can have some side-effects .Has anyone tells me what's the side-effects?

es.read.field.include only impacts two things at the moment: 1) filtering of array values returned with the document source, and 2) used to determine array depth for Spark SQL's schema conversion code.
