v2.0 Breaking changes

This section discusses the changes that you need to be aware of when migrating your application to Elasticsearch 2.0.

여기에서는 application을 Elasticsearch 2.0으로 migration할 경우 알아야 할 변경 사항에 대해 이야기한다.

Indices created before 0.90edit

Elasticsearch 2.0 can read indices created in version 0.90 and above. If any of your indices were created before 0.90 you will need to upgrade to the latest 1.x version of Elasticsearch first, in order to upgrade your indices or to delete the old indices. Elasticsearch will not start in the presence of old indices.

Elasticsearch 2.0은 v0.90 이상에서 생성된 indices만을 읽을 수 있다. v0.90 이전에서 생성된 indices는 indices를 uprade하기 위해, 먼저 v1.x로 upgrade해야 한다. Elasticsearch는 오래된 버전으로 생성된 indices가 있으면, 시작되지 않는다.

Elasticsearch migration pluginedit

We have provided the Elasticsearch migration plugin to help you detect any issues that you may have when upgrading to Elasticsearch 2.0. Please install and run the plugin before upgrading.

Elasticsearch 2.0으로 upgrade할 경우, 예상되는 issue를 찾는데 도움이 될 수 있도록, Elasticsearch migration plugin을 제공한다. upgrade 전에 이 plugin을 설치하고 실행해 보기 바란다.
