Hi,  
Im trying to install Elasticsearch 6 on windows using .zip file. I unzipped the file, tried running it from cmd using elasticsearch.bat and initially got an error with JAVA\_HOME. So downloaded JDK 9 ,pointed the location and tried running it again. Now I get an error that says :  
Java HotSpot(TM) 64-Bit Server VM warning: Option UseConcMarkSweepGC was deprecated in version 9.0 and will likely be removed in a future release.

What should I do next ? Should I try the previous version of Java ?

Any help would be much appreciated.

Thanks and Regards,  
Rahul

We don't support Java 9 at the moment, please use Java 8.

How did you set it? What OS are you on?
