I'm using the mapr sandbox to test upgrading our cluster. I've had a lot of trouble getting it to run under VMWare/ESXi because my first instinct was to add ram/cpus. I upped it to 8 cores and 64 GB ram, reboot and MCS won't come up. I put the cores back to 2, reboot and it is still no good. So I drop the ram back to 8GB, reboot and it's all good again. Does anyone know what is going on there?
