Elasticsearch Migration Plugin - Custom Aggregation Plugin

Deb · October 9, 2017, 6:07am

I am trying out the elasticsearch migration plugin to check if I can migrate from 2.3.x to 5.x. I have some custom aggregation plugin in my 2.3.x cluster.

Running "Cluster Check-up" it is showing green for "Plugins".

So my question is does the elasticsearch migration plugin verifies all the plugins including custom plugins?

The plugin only verifies the plugins it knows about
https://www.elastic.co/guide/en/elasticsearch/reference/5.0/breaking_50_plugins.html

Looking into the sources, you can see all the plugin checks it does and that does not include custom ones, unless it is a site plugin, in which case, it would warn you.

github.com

elastic/elasticsearch-migration/blob/2.x/src/migration/Plugins.js

"use strict";

function Plugins() {

  function site_plugins(plugins) {
    return check_array(
      'yellow',
      'Site plugins are no longer supported',
      plugins,
      function(p) {
        if (p.site && p.name !== 'elasticsearch-migration') {
          return p.name
        }
      },
      'https://www.elastic.co/guide/en/elasticsearch/reference/5.0/breaking_50_plugins.html#_site_plugins_removed');
  }

  function removed_plugins(plugins) {
    var names = {
      "discovery-multicast" : "The `discovery-multicast` plugin has been removed",

I would enable deprecation logging in order to see if your custom aggregation plugin raises any red flags.

HI @Deb

I am trying to write a custom aggregation plugin. I am just roaming around to find any help.

Can you please share something, I mean how can I do that. I am totally clueless, where to start from.

Thanks!
