dynamic mapping for nested type - elasticsearch

Question

I have an index/type of test1/all which looks as follows:
{
"test1": {
"mappings": {
"all": {
"properties": {
"colors": {
"properties": {
"H": {"type": "double"},
"S": {"type": "long"},
"V": {"type": "long"},
"color_percent": {"type": "long"}
}
},
"file_name": {
"type": "string"
},
"id": {
"type": "string"
},
"no_of_colors": {
"type": "long"
}
}
}
}
}
}
I would like to make the colors field nested, I am trying the following :
PUT /test1/all/_mapping
{
"mappings":{
"all":{
"properties": {
"file_name":{
"type": "string",
"index": "not_analyzed"
},
"id": {
"type": "string",
"index": "not_analyzed"
},
"no_of_colors":{
"type":"long",
"index": "not_analyzed"
},
"colors":{
"type":"nested",
"properties":{
"H":{"type":"double"},
"S":{"type":"long"},
"V":{"type":"long"},
"color_percent":{"type":"integer"}
}
}
}
}
}
}
But I get the following error:
{
"error": "MapperParsingException[Root type mapping not empty after parsing!
Remaining fields: [mappings : {all={properties={file_name={type=string, index=not_analyzed}, id={type=string, index=not_analyzed}, no_of_colors={type=integer, index=not_analyzed}, colors={type=nested, properties={H={type=double}, S={type=long}, V={type=long}, color_percent={type=integer}}}}}}]]",
"status": 400
}
Any suggestions? Appreciate the help.

You're almost there, you simply need to remove the mappings section like this:
PUT /test1/all/_mapping
{
"properties": {
"file_name": {
"type": "string",
"index": "not_analyzed"
},
"id": {
"type": "string",
"index": "not_analyzed"
},
"no_of_colors": {
"type": "long",
"index": "not_analyzed"
},
"colors": {
"type": "nested",
"properties": {
"H": {
"type": "double"
},
"S": {
"type": "long"
},
"V": {
"type": "long"
},
"color_percent": {
"type": "integer"
}
}
}
}
}
However, note that this will not work either, because you cannot change the colors type from object to nested and the other string fields from analyzed to _not_analyzed. You need to delete your index and re-create it from scratch
