Description

We need a Freon tool to simulate a number of datanodes and coordinate with SCM to create a number of containers on the simulated datanodes. This will help to verify the capability of SCM to handle thousand of nodes and exabytes of data.

Example usage: a simulation of 5K datanodes with 40K containers per datanode, i.e. simulating 1 exabyte of raw data.
