I have a question. Recently I ran across this post where someone configured a MapR single node cluster on CentOS with 4 GB of RAM.
I tried to follow the same steps with the installer, only with a different OS (Ubuntu) and double the RAM (8 GB) using
option - 5.2.2 (and yes, including a second disk) and it failed on the RAM of all things.
Why did this happen when the example in the post above used less than half the RAM? Is RAM per node configurable anywhere with the installer?
