Subject Re: Minimum CPU and RAM for Cassandra and Hadoop Cluster
Date Wed, 17 Jul 2013 15:42:51 GMT
Even if we have one machine, will splitting it up into 2 nodes via a VM
make a difference ?
Can it simulate 2 nodes of half the computing power ? Also, yes, this will
just be a test playground
and not in production.

Thank you,

Martin
