I have installed 5.6.4 Zip file. While starting Elasticsearch getting below error

./bin/elasticsearch  
Error: encountered environment variables that are no longer supported  
Use jvm.options or ES\_JAVA\_OPTS to configure the JVM  
ES\_HEAP\_SIZE=10g: set -Xms10g and -Xmx10g in jvm.options or add "-Xms10g -Xmx10g" to ES\_JAVA\_OPTS

I have set the Heap Size in JVM.options as 15g. Please find the below.

In JVM.options i have set the below

```
# Xms represents the initial size of total heap space
# Xmx represents the maximum size of total heap space
     
-Xms15g
-Xmx15g

```

Please help me out.

Did you remove `ES_HEAP_SIZE`?  
If so, what is the error message you are getting now?

And don't set both: `jvm.options` AND `ES_JAVA_OPTS`. It's useless and you will never know which one is used at the end.

Thanks for your help.

I have removed ES\_HEAP\_SIZE in the environmental variables. Now it is working.

Thanks once again.
