How to handle dot in field names in ES 7.0

(shashank) #1

I was recently hit by the fieldname-with-dots issue in ES. I search on google but found the answer for ES 2.X version while for other version none of the option work for me.

execution.command = /bin/bash
execution.command.args = emrStatusCluster

"Note : type_name is deprecated for ES 7.0 so default type is _doc "

I use curl -XPOST localhost:9200/index_name/_doc -H "Content-Type: application/json" -d @jsondata.json to load data and get following mssg on the console.

{"error":{"root_cause":[{"type":"illegal_argument_exception","reason":"Can't merge a non object mapping [execution.command] with an object mapping [execution.command]"}],"type":"illegal_argument_exception","reason":"Can't merge a non object mapping [execution.command] with an object mapping [execution.command]"},"status":400

I tried dot_expander but didnot find anything much useful and constructive.

Thanks in Advance ,

What do you have in jsondata.json?

A single Json record in which execution.command and execution.command.argrs are present somewhere as key.

You need to fix its content probably.

I don't have any control on content since content comes from nifi where i call elastic search api is there any way to deal as it is given for ES 2.X version where we can allow dot in field name.

Thanks in advance.

I don't really know as I can't see the content.

Ok let me give you small view of Content which is in json format:


Now the problem is execution.command.args and execution.command both contain data if i make execution.command type as object then on running it will give error what i did is :

PUT index_try
  "mappings": {
    "json": {
      "properties": {
        "created_at": {
          "type": "date",
          "format": "yyyy-MM-dd HH:mm:ss||yyyy-MM-dd||epoch_millis"
        "execution": {
          "type": "object",
          "properties": {
            "command": {
              "type": "object",
              "properties": {
                "args": {
                  "type": "text"
  "settings": {
    "number_of_shards": 6,
    "number_of_replicas": 1
