Hi,
I'm trying to run elasticsearch on my mac but it fails due to java version incompatibility.
The thing is that I have the latest version of Java installed on my system ( 8 Update 144 ) but I keep getting this error when starting the elasticsearch server:
`Elasticsearch requires at least Java 8 but your Java version from /usr/bin/java does not meet this requirement`
Any ideas how to solve this?
Thanks.

Hi,
can you try out what is the output of
> /usr/bin/java -version
What your system ? Which distribution ?

You're trying to use JDK 6 to start Elasticsearch, and the output message makes clear that we require JDK 8. You need to set `JAVA_HOME` to point to your JDK 8 installation. Right now you either do not have that set and the first one in the path is being picked up which appears to be a JDK 6 installation, or you have it set and pointing to JDK 6. Either way, please point `JAVA_HOME` to JDK 8.

Those are put there if you browse the directory through Finder.
