I set up a simple virtual cluster using 4 VMs and installed CM 4 on it.
It got to the "first run" - step 8 of 10 - and then hung. Turned out the VM
assigned the role of master had run out of heap and the OOM killer was
lopping off processes at the head. I ran out of time and turned off the VMs.
Question: what now is the state of the cluster? Assuming I allocate more
heap to the master node, will I be able to continue with the setup where I
left off, or should I start over?
