I try to make an index using the JAVA API like this

```
        cl.admin().indices().prepareCreate("index")
            .setSettings(settingsBuilder)
            .addMapping("event", mappingBuilder)
            .get();

```

but i get this exception Caused by: [index/fQUXl2xIT6CQcAuE4EMQGw] ResourceAlreadyExistsException[index [index/fQUXl2xIT6CQcAuE4EMQGw] already exists]

when i go after to kibana i see my index is there, and when i comment out the above lines there is no index in kibana

If the index already exists, you can't create it again.

Apparently no.

May be something wrong in your code? Like you are calling two times the same code?
