I am trying to index a json field in elastic search, I have given it external mapping that this field should be treated as string and not json, also indexing is not required for it, so no need to analyze it. The mapping for this is following
"json_field": {
"type": "string",
"index": "no"
},
Still at the time of indexing, this field is getting analyzed and because of that I am getting MapperParsingException
in Short How can we store json as a string in elastic search without getting analyzed ?

JSON exists as a string — useful when you want to transmit data across a network. It needs to be converted to a native JavaScript object when you want to access the data.
To import a JSON file into Elasticsearch, we will use the elasticdump package. It is a set of import and export tools used for Elasticsearch. It makes it easier to copy, move, and save indexes. To install elasticdump , we will require npm and Node.
Elasticsearch offers simple REST based APIs, a simple HTTP interface, and uses schema-free JSON documents, making it easy to get started and quickly build applications for a variety of use-cases.
Elasticsearch has the ability to be schema-less, which means that documents can be indexed without explicitly providing a schema. If you do not specify a mapping, Elasticsearch will by default generate one dynamically when detecting new fields in documents during indexing.
Finally got it, if you want to store JSON as a string, without analyzing it, the mapping should be like this
"json_field": {
"type": "object",
"enabled" : false
},
The enabled flag allows to disable parsing and indexing a named object completely. This is handy when a portion of the JSON document contains an arbitrary JSON which should not be indexed, nor added to the mapping.
Update - From ES version 7.12 "enabled" has been changed to "index".
