could not find java; set JAVA_HOME or ensure java is in PATH
After reading the docs from ElasticSearch, I found that if you're running on Ubuntu or Debian, the package only ships with the OpenJDK because of licensing issues. To fix this Java path problem, I installed the following after installing ElasticSearch (as directed by the docs): sudo add-apt-repository ppa:webupd8team/java sudo apt-get update sudo apt-get install oracle-java8-installer java -version Then upon running sudo service elasticsearch start everything worked and I had no more Java path issues.
