2. ./prepareMasterSlaves to get ready for master, slave and candidates.

elasticDB run

1. From eclipse, just run without any parameter
2. Or, from eclipse, in order to test scalability run with -c
3. Or, from eclipse, in order to test availability and scalability run with -c -d
4. Or, you can also run from CommandLine accordingly
