I am looking to run elasticsearch by running elasticsearch.bat file in bin folder  
but its throwing following error,  
**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.**  
**Error: Could not find or load main class Kumar**  
**Caused by: java.lang.ClassNotFoundException: Kumar**

Mohan Kumar U is the user name, and i am running windows, java 11,  
I have also set JAVA\_HOME in environment variables

Which elasticsearch version is that?

I'd recommend moving elasticsearch to a directory without any space in its name.  
Not sure if that will fix the problem but worth trying.  
Same for Java.

You can also may be look at [https://www.elastic.co/guide/en/elasticsearch/reference/current/windows.html](https://www.elastic.co/guide/en/elasticsearch/reference/current/windows.html)?
