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

```
{  
   "s3.version":"mc5ETuM",
   "invokehttp.tx.id":"f75283d92c",
   "sqs.receipt.handle":"Zl/yWciVceGIiWiC5sNkQ=",
   "Server":"J4)",
   "s3.etag":"712a41",
   "listEMResponse":"",
   "indexed_file_path":"fasfd",
   "schemaName":"",
   "uuid":"cf",
   "sqs.message.id":"ae",
   "sqs.SenderId":"AI",
   "hash.value":"7b77",
   "tableName":"Table1",
   "execution.command":"/bin/bash",
   "filename":"1554448956907.csv",
   "s3.key":"/15544_TB_.csv",
   "execution.command.args":".-1"
}

```

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
  }
}

```
