Settings Memory Size for some specific Oozie Action

[#1]

I have set java-opts parameters in my ozzie action's xml file.

It looks like

            <java-opts> -XX:MaxPermSize=128m -XX:+PrintGCDateStamps -XX:+PrintGCTimeStamps -XX:+PrintGCDetails </java-opts>

On my local cluster this set of parameters works ok, but on production environment looks like they are out of order, I dont know why.

Is there a way to understand:

1) why my set of parameters is not applied

2) what are the parameters of JVM my job is laucnhed with

3) how can I force Oozie to use my set of parameters

?
