> I am new to Elastic search and facing an issue while installing it. I am getting below exception: org.elasticsearch.bootstrap.StartupException: ElasticsearchException[Failed to create native process factories for Machine Learning]; nested: FileNotFoundException[\.\pipe\controller\_log\_13044 (The system cannot find the file specified)]; Can anyone suggest me what can i do to resolve the same? Thanks & Regards, Priyanka Y.

Nothing of interesting..

File liblog4cxx.so.10 exists on **my** system without changes. I think he is not guilty of anything. I think the system is trying to create something in the /tmp directory for the running Learning Machine, but cannot do it, so the process crashes.  
The problem is that I don't know if I need a learning machine or not? 🤪  
I am trying other temp-directory with owner "elasticsearch", changing version of Java, but don`t understand, why this "very bad" process cannot running. 😡

I will patiently study the documentation. 😇  
If I can understand, I will write here.
