org.elasticsearch.bootstrap.StartupException: ElasticsearchException [Failure running machine learning native code

Elastic Stack Elasticsearch

Hi I am new to elastic search. Currently, I am doing a project that requires machine learning functionality in elasticsearch. Here is the error I get:

Does anyone know how to resolve it?

It could be due to running on an unsupported OS or distribution, missing OS libraries, or a problem with the temp directory.

What OS are you running on?

If you do not want to spend any time on troubleshooting then you can run Elasticsearch without machine learning functionality by setting xpack.ml.enabled: false in your elasticsearch.yml.

In terms of your suggestions, I actually tried xpack.ml.enabled: false before. Although the error no longer exist, the project I work on actually needs the machin learning functionality. So I guess we have to figure out another way to make it work.

Here is my system config:

Oh, you're on a Mac.

I suspect this may be something related to Apple's notarization requirements - any program downloaded from the internet that's not signed by Apple will be instantly killed when it runs.

If that's the problem you can try this from the top level of the install:

find . -exec xattr -d com.apple.quarantine '{}' ';'

That will remove the attribute that remembers that the install was downloaded from the internet.

If that doesn't fix it, try find . -name autodetect from the top level of your install, then change to the directory where the autodetect program is found and run ./autodetect --version. Does that print the version or crash with some OS error? If it crashes then the error will give a good idea what to do next.
