Change in index_in_parent doesn't work, but throws no error #53792
Description
Elasticsearch version (bin/elasticsearch --version): 6.8.6 / 7.6.0
Description:
Trying to change the value of index_in_parent seems to succeed, but doesn't.
I would expect that it is working as designed that that value cannot be changed, but I think it's a bug that no error is returned when trying to change it.
Steps to Reproduce:
PUT /parenttest
PUT /parenttest/_mapping/_doc
{
"properties": {
"email": {
"type": "keyword"
},
"user" : {
"type" : "nested",
"include_in_parent": true,
"properties": {
"first" : {"type": "text" },
"last" : {"type": "text" }
}
}
}
}
GET parenttest
PUT /parenttest/_mapping/_doc
{
"properties": {
"email": {
"type": "keyword"
},
"user" : {
"type" : "nested",
"include_in_parent": false,
"properties": {
"first" : {"type": "text" },
"last" : {"type": "text" }
}
}
}
}
GET parenttest
Expected behaviour:
The third PUT returns an error explaining that it's not possible to change the value of "include_in_parent"
Observed Behaviour:
None of the calls throws an error.
The second GET returns exactly the same data as the first.

Thanks @AndyHunt66 for reporting this. I agree that we should throw an error when attempting to change the values for these parameters. The alternative is to add support for changing the value. This would allow for a situation in which some documents contain the values in the parent/ root but others do not, which is a strange index state and could cause confusion when querying against these fields.
