Elasticsearch java 8 check fail

Elastic Stack Elasticsearch
1

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 ?

3

/usr/bin/java -version
OUTPUT: Java(TM) SE Runtime Environment (build 1.6.0_65-b14-468-11M4833)
Java HotSpot(TM) 64-Bit Server VM (build 20.65-b04-468, mixed mode)

Mac OS 10.12.6

Ok, then elastic check ist working well.

reboot ? And make sure rigth java version is on be path

5

reboot did not fix the problem. Error persists

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.

Got it to work.

I just had to delete the '.DS_Store' file from /modules

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