Thanks I reformatted the stack trace. I was reading here: https://www.elastic.co/guide/en/elasticsearch/reference/2.0/setup-dir-layout.html
It shows the path.repo setting is empty by default. Since I'm not explicitly setting this value, I think that is why I'm seeing this warning then correct? I'm just wondering if that is ok or if this path.repo should have a default value. Sounds like you are suggesting to set this value? Overall, I don't think I noticed this warning before so it just has me a little more curious now. Thanks again!
