CentOS Linux release 7.2.1511 (Core)

openjdk version "1.8.0\_102"  
OpenJDK Runtime Environment (build 1.8.0\_102-b14)  
OpenJDK 64-Bit Server VM (build 25.102-b14, mixed mode).

ES\_HEAP\_SIZE is no longer used and I noticed differences in the init.d script between 2.4 and the 5.0 RC.

The 2.4 init.d script has this in it which 5.0 RC does not:

```
...
start() {
    checkJava
    [-x $exec] || exit 5
    if [-n "$MAX_LOCKED_MEMORY" -a -z "$ES_HEAP_SIZE"]; then
        echo "MAX_LOCKED_MEMORY is set - ES_HEAP_SIZE must also be set"
        return 7
    fi
...

```

I'm confused about how its using ES\_HEAP\_SIZE here.

You have to edit `config/jvm.options` to set `-Xms` and `-Xmx` to another default, or use `ES_JAVA_OPTS` environment variable.

I know that, but I was just curious what init.d script is actually doing with the vault
