ElasticSearch and Java environment variable

Question

For Windows 7, I\'ve installed JDK in both 32 and 64 bit versions. The versions are 8, update 20 for all four installations. http://www.oracle.com/technetwork/java/javase/d

Answer 1

This is pretty common error, JAVA_HOME environment is not set. So, we need to set it up in a more prominent basis. What it's asking for the path to the jre directory and not to the bin directory i.e. java environment path to configure & run the elasticsearch. So, make sure you don't specify the bin directory into your path. Then, you are good to go run your elasticsearch and it will be up and running at default port 9200.
