Is there any particular recommendation against giving different nodes a different amount of heap ?
I have a cluster with 10 nodes, each has 32Go of RAM but 2 have - for now - only 24Go
I would like to maximize the heap on each node so give 16Go to the 32Go nodes and 12Go to the 24Go nodes (and maybe find a way to prioritize high heap nodes for some queries)
Is it not recommended ? Would it be better to give 12Go to all nodes ?
Is there an environment variable I can use in jvm.options to specify that I want half the RAM on all nodes ?
