@QqGeet your problem is the same as [Failed to start Machine Learning on Elasticsearch 7.0.0](https://discuss.elastic.co/t/failed-to-start-machine-learning-on-elasticsearch-7-0-0/178216/8) - we require SSE4.2 instructions to use Elastic machine learning and the machine you're running on doesn't have these. You'll have to run on a more recent machine if you want to use machine learning.

@Cadu_Alves if you could post the output from running `controller` directly we can try to diagnose your problem too.

In both cases, if you are not intending to use machine learning, put `xpack.ml.enabled: false` in your `elasticsearch.yml` and then Elasticsearch will start and you can use the other features. We're intending to improve the error message to say this - see [https://github.com/elastic/elasticsearch/issues/42341](https://github.com/elastic/elasticsearch/issues/42341).
