Yes, this kind of message is not welcome on this list. At best the wording is ... odd, but the tone is combative. It's not even clear what the question is. This user has posted several other messages with the same type of issue, uncannily like those of "Zahid Raman" last month.
This list has thousands of people and is a shared resource. Please everyone take time to ask a clear question, politely. Keep it on topic and constructive. We do take action against posters who abuse the list. Now, if the question is "what is on vs off heap memory", then you should probably start by understanding the JVM and what the heap is, and that Java applications normally allocate memory on the heap but can also allocate directly off the heap. Spark does this. I'm not even sure what the analogy to a light switch means.
