> {{JavaLaunchCommandBuilder}} sets the default path to the Java executable  in this way:
> {code:java}
> private static final String DEFAULT_JAVA_PATH = System.getenv("JAVA_HOME") + "/bin/" + "java";
> {code}
> That is, *by default* REEF client assumes that
>   1) you have {{JAVA_HOME}} environment variable set, and
>   2) your {{JAVA_HOME}} is the same as the one on the remote host.
> A better solution would be to set
> {code:java}
> DEFAULT_JAVA_PATH = "java";
> {code}
> and assume that java binary is in the system's {{PATH}} - both on the client and in the cluster.
