Elastic Search mapper_parsing_exception error - elasticsearch

Question

I have created a index in elastic search with name test. Index mapping is as follow:
{
"title": {
"type": "text",
"fields": {
"raw": {
"type": "keyword"
}
}
},
"url": {
"type": "text",
"fields": {
"raw": {
"type": "keyword"
}
}
}
}
after creating index I have added following documents into it:
{
"title": "demo",
"url": {
"name": "tiger",
"age": 10
}
}
But I am getting following error:
{"mapper_parsing_exception","reason":"failed to parse field [url] of
type [text]"}
can anyone help me into this?

Answer 1

If your documents look like this:
{
"title": "demo",
"url": {
"name": "tiger",
"age": 10
}
}
Then your mapping needs to look like this, i.e. url is an object with the name and age fields:
{
"title": {
"type": "text",
"fields": {
"raw": {
"type": "keyword"
}
}
},
"url": {
"properties": {
"name": {
"type": "text",
"fields": {
"raw": {
"type": "keyword"
}
}
},
"age": {
"type": "integer"
}
}
}
}

Hi You need to create mapping like this
PUT test
{
"settings" : {
"number_of_shards" : 1
},
"mapping": {
"title": {
"type": "text",
"fields": {
"raw": {
"type": "keyword"
}
}
},
"url": {
"type": "text",
"fields": {
"raw": {
"type": "keyword"
}
}
}
}
}
And the document is
put test/doc/1
{
"title": "demo",
"url": {
"name": "tiger",
"age": 10
}
}
GET test/doc/1
And the result is
{
"_index" : "test",
"_type" : "doc",
"_id" : "1",
"_version" : 1,
"_seq_no" : 0,
"_primary_term" : 1,
"found" : true,
"_source" : {
"title" : "demo",
"url" : {
"name" : "tiger",
"age" : 10
}
}
}

One reason for this if you're on Elastic Cloud is that the data types are assigned to fields the first time they appear on an index. And it will throw this error if you send it a subsequent log with a different type in that field.
For me, the log field was a string in the first log sent to the index but an object in the second. So the second one got rejected.
