Hi,
I'm trying to put the following mapping using the Java API :
{
"userprofile" : {
"\_id" : {
"path" : "\_mid"
},
"properties" : {
"\_mid" : {
"type" : "string",
"store" : "yes",
"index" : "not\_analyzed"
}
}
}
}
When checking what mapping is known server side I get :
mappings: {
userprofile: {
properties: {
\_mid: {
index: not\_analyzed
store: yes
type: string
}
}
}
}
There is no reference to the \_id field ....
Here's how this is done in JAVA :
XContentBuilder mappingBuilder = XContentFactory.jsonBuilder()
.startObject()
.startObject("userprofile");
mappingBuilder.startObject("\_id");
mappingBuilder.field("path", "\_mid");
mappingBuilder.endObject();
mappingBuilder.startObject("properties");
mappingBuilder.startObject("\_mid");
mappingBuilder.field("type", "string");
mappingBuilder.field("store", Store.yes);
mappingBuilder.field("index", Analyze.not\_analyzed);
mappingBuilder.endObject();
getClient().admin().indices()
.preparePutMapping().setType("userprofile")
.setSource(mappingBuilder.string()).execute().actionGet();
getClient().admin().cluster().prepareHealth().setWaitForGreenStatus().execute().actionGet();
What am I doing wrong ?
Why isn't the "\_id" mapping taken into account ?
Thanks for your help.
Alex

Sorry for the noise ... I was in 0.17.9 ... just upgraded to 0.18.3
and it works perfectly now
Cheers
