Review comment:
this is required because each individual test case in TestDataValidate sets
this parameter in the RandomKeyGenerator builder.

> Goal:
> It can be useful to exercise the IO and control paths in Ozone for simulated
> large datasets without having huge disk capacity at hand. For example, this
> will allow us to get things like container reports and incremental container
> reports, while not needing huge cluster capacity. The
> [SimulatedFsDataset|https://github.com/apache/hadoop/blob/trunk/hadoop-hdfs-project/hadoop-hdfs/src/test/java/org/apache/hadoop/hdfs/server/datanode/SimulatedFSDataset.java]
> does something similar in HDFS. It has been an invaluable tool to simulate
> large data stores.
