> Key: HDDS-1094
> URL: https://issues.apache.org/jira/browse/HDDS-1094
> Project: Hadoop Distributed Data Store
> Issue Type: Improvement
> Components: Ozone Datanode
> Reporter: Supratim Deka
> Assignee: Supratim Deka
> Priority: Major
> Labels: pull-request-available
> Time Spent: 1h 20m
> Remaining Estimate: 0h
>
> 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.
