How to define mappings using Java API

Could someone share a working example of using the Java API to define
type mappings?

I'm trying things like:
Settings.Builder indexSettings =
ImmutableSettings.settingsBuilder().loadFromSource( XContentFactory.jsonBuilder()
.startObject()
.startObject("settings")
.startObject("index")
.field("number_of_shards","BOGUS")
.endObject()
.endObject()
.startObject("mappings")
.startObject("my_type_name")
.startObject("sequence")
.field("type",
"boolean")
.endObject()
.startObject("message.text")
.field("type",
"string")
.field("index",
"no")
.endObject()
.endObject()
.endObject()
.endObject().string());

CreateIndexResponse createIndexResponse = client.admin().indices()
.prepareCreate(newSlice).setSettings(indexSettings)
.execute().actionGet();

I haven't managed to twiddle the builder structure such that they take
effect. E.g. message.text is searchable despite not being index,
sequence accepts numbers despite being boolean, and number_of_shards
being set to BOGUS doesn't produce any errors.

Thanks

Hi Lorrin,

Have a look here :
https://github.com/dadoonet/rssriver/blob/master/src/test/java/org/elasticse
arch/river/rss/AbstractRssRiverTest.java
Create the index with an abstract mapping() method

And here :
https://github.com/dadoonet/rssriver/blob/master/src/test/java/org/elasticse
arch/river/rss/RssRiverTest.java
(for an implementation of the mapping() method)

HTH
David.

Hi David,

That helped, thanks. After getting the builder stuff working following
the example, I switched over to supplying the settings as a JSON
string with the following command:
CreateIndexResponse createIndexResponse =
client.admin().indices()
.prepareCreate(indexName)
.setSettings(elasticSearchSettings)
.addMapping(elasticSearchType,
elasticSearchMappings)
.execute().actionGet();

where elasticSearchSettings is:
{
"index" : {
"number_of_shards" : 2,
"number_of_replicas" : 1
}
}

and elasticSearchMappings is in the format
{
"" : {
"properties" : {
"<column_name>" : {
"type" : ...
},
...
}
}

I wasn't able to apply settings using a nested Java Map<String,Object>
structure, but I'm happy with supplying the JSON.

Cheers

This was quite helpful.

I do have one question though. Is elasticSearchMappings of type Settings?
