zjffdu edited a comment on issue #3442: [ZEPPELIN-4283] Choose which server to run the interpreter process URL: https://github.com/apache/zeppelin/pull/3442#issuecomment-530422764 This is what I concern. Why do you think choosing A is correct ? IIUC, we have to assume that A,B,C have the same computing resources (cpu cores and memory) and besides that we also assume all the interpreter processes consume the same amount of memory. But I don't think these assumptions are true in reality. Do you know how much gap between the actual memory and the number calculated by java ? It is weird to me that we can not get the free memory programmatically, it is a very common problem.
