Version: Elasticsearch 7.2.0 System info: CentOS Linux release 7.6.1810 (Core) On starting elasticsearch, I'm getting this error log - ``` [2019-07-14T14:00:26,398][WARN][o.e.b.ElasticsearchUncaughtExceptionHandler] [fermium] uncaught exception in thread [main] org.elasticsearch.bootstrap.StartupException: ElasticsearchException[Failed to create native process factories for Machine Learning]; nested: FileNotFoundException[/tmp/elasticsearch/controller_log_28381 (No such file or directory)]; ``` Elasticsearch Startup options - ``` ES_TMPDIR=/tmp/elasticsearch ./elasticsearch ``` I read somewhere that it should have read/write/execute permissions to the /tmp/elasticsearch directory, it has those already - ``` # ls -lhd /tmp/elasticsearch drwx------ 3 abhinav2 abhinav2 4.0K Jul 14 14:02 /tmp/elasticsearch ``` **If I disable xpack ml, it works fine** : That is, if i add `xpack.ml.enabled: false` to elasticsearch.yml, it works fine.

Hello - the easiest way to debug this is to find and execute `controller` from the prompt: - first with `--version` as a command-line argument ( i.e. `/path/to/modules/x-pack-ml/platform/linux-x86_64/bin/controller --version` ) - then again without the `--version` argument Report what the output is and post back. Thanks! ---

See: [Elasticsearch 7.1.1 Failed to create native process factories for Machine Learning](https://discuss.elastic.co/t/elasticsearch-7-1-1-failed-to-create-native-process-factories-for-machine-learning/184006/5) Looks like you are attempting to run on an older machine that does not have support for the SSE4.2 instruction sets. ---
