Setting up mapping for a JDBC elasticsearch river

问题

I'm using ES 0.20.6 with the elasticsearch-river-jdbc plugin. I created a river that works using :

SQL="SELECT ..."
curl -XPUT 'localhost:9200/_river/myindex_river/_meta' -d '{
    "type" : "jdbc",
    "jdbc" : {
        "driver" : "org.postgresql.Driver",
        "url" : "jdbc:postgresql://localhost:5432/mydb_db",
        "user" : "myuser",
        "password" : "mypassword",
        "sql" : "'"$SQL"'"
    },
    "index" : {
        "index" : "myindex",
        "type" : "mytype",
        "type_mapping" : null
    }
}'

Now what i want is to add type mappings as the option is defined in the plugin documentation. But i really cant't figure out the syntax and always get the following error (with the "Source: " part varying depending on my attempts)

I think you are submitting something that is not even a proper json object. I can imagine the type_mapping object has to contain the mapping, pretty much the same mapping that you would submit using the put mapping api otherwise, or creating the index.
