Elasticsearch 1.3. - Call custom REST endpoint from Java -


i building elasticsearch plugin exposes rest endpoint ( starting post )

i can call endpoint curl :

curl -x post 'http://my-es:9200/lt-dev_terminology_v1/english/_terminology?pretty=-d '{     "segment": "database",     "analyzer": "en_analyzer" }

my question how can call same endpoint java, using transport client ? point me tutorial ?

i suggest take here. should starting point you.

let me sum :

considering following parameters :

string clustername = "..."; string clienttransporthost = "..."; integer clienttransportport= "..."; string clientindex = "..."; string indextype = "...";

of course replace dots settings wish use.

then define cluster settings:

settings settings = immutablesettings.settingsbuilder()         .put("cluster.name", clustername).build();

you instantiate transportclient object :

    transportclient client =  new transportclient(settings); client.addtransportaddress(new inetsockettransportaddress(clienttransporthost, clienttransportport));

you can verify connection using method :

private void verifyconnection(transportclient client) {     immutablelist<discoverynode> nodes = client.connectednodes();     if (nodes.isempty()) {         throw new elasticsearchexception(                 "no nodes available. verify es running!");     } else {         log.info("connected nodes: " + nodes.tostring());     } }

ps: use log.info() method have instantiate logger.

so can use verification method :

verifyconnection(client);

and once you've done can per example prepare search :

searchresponse response = client.preparesearch(clientindex)             .settypes(indextype)                             .addfields("...", "...")             .setsearchtype(searchtype.default)                             .execute()                             .actionget();

ps : tested on elasticsearch 1.3

commonjs - How to write a typescript definition file for a node module that exports a function? -

consider, toml node module can use: // toml.d.ts declare module toml { export function parse(value:string):any; } declare module "toml" { export = toml; } then: /// <reference path="../../../../../defs/toml/toml.d.ts"/> import toml = require('toml'); toml.parse(...); however, node module export single function, such 'glob' ( https://github.com/isaacs/node-glob ). the node usage of module be: var glob = require("glob") glob("*.js", {}, callback(err, files) { ... }); you'd naively expect this: // glob.d.ts declare function globs(paths:string, options:any, callback:{(err:any, files:string[]):void; ...but because typescripts 'import' semantics bit strange, seems can use 'import .. = require()' statement alias modules . trying call: /// <reference path="../../../../../defs/glob/glob.d.ts"/> import blog = require('glob'); results in: error ts2072: mod...
