Hello

I'm trying to start Java in Server VM mode for elasticsearch but no  
success

Ubuntu 10.04.4 LTS

/etc/environment file is set environment variable  
ES\_JAVA\_OPTS="-server"

echo $ES\_JAVA\_OPTS shows  
-server

in elasticsearch.conf file  
set.default.ES\_JAVA\_OPTS=-server

java -showversion -server  
java version "1.6.0\_20"  
OpenJDK Runtime Environment (IcedTea6 1.9.13)  
(6b20-1.9.13-0ubuntu1~10.04.1)  
OpenJDK Server VM (build 19.0-b09, mixed mode)

but in elasticsearch,conf file is still error  
[WARN][bootstrap] jvm uses the client vm, make sure  
to run `java` with the server vm for best performance by adding `- server` to the command line

Which is the correct place to put -server command line option ?

Kuido

If you run it without the wrapper does it work? You can't set the  
ES\_JAVA\_OPTS with teh Java service wrapper, you might need to add it  
explicitly in the JVM configs later on in the wrapper configuration.
