Reindex java API

Elastic Stack Elasticsearch
1

Hi.
Is the java API updated with the new reindex API?

2

Reindex is actually a module (plugin shipped with Elasticsearch) so it is slightly less well integrated with the java API. Calling it looks like:

ReindexAction.INSTANCE.newRequestBuilder(client()).source("index1", "index2").destination("dest").get();

It gets less fluent when you want to be very specific:

ReindexRequestBuilder builder = ReindexAction.INSTANCE.newRequestBuilder(client()).source("index1", "index2").destination("dest");
builder.source().setScroll("20m").setRouting("candycane");
builer.get();

Do I have to install the module? I have installed elasticsearch 2.3 and I have a folder under modules in the install directory where the reindex jar file is.
When I try to use it im my application I get a nullpointerexception. Can you please assist?

Can you share your code for no.logiq.finfo.elastic.ArticleReindexTest.reindex()?

Hello,

In my case, I'm able to use Reindex API as follows:

  1. Start an ElasticSearch master manually,
  2. Create TransportClient (adding ReindexPlugin)
    TransportClient client = TransportClient.builder().settings(settings).addPlugin(ReindexPlugin.class).build();
  3. Use Reindex API inside my app. as Nik commented.

HTH,

Trango
