HDSL allows different kind of storage systems to be built on an HDFS cluster. Ozone is is a distributed key-value store built using HDSL.

...

Ozone is a work in progress and currently in alpha state. To test it you needneed to build if from the source code or use Hadoop version higher than 3.1.

...

To run an Ozone cluster you have multiple optionoptions:

1. Use prebaked docker images from the dockerhub docker hub (no build is required, but these images are not from the Apache Hadoop project)

2. Build a new Ozone cluster from the source code and start a cluster with docker (also useful for development)
3. Build new Ozone cluster from the source code and start it with the startup scripts without docker.

...

• To follow the progress of Ozone development you can check the JIRA dashboard

• All the discussions/substaskssubtasks/original design documents are available from the feature branch jira:

  Jira
  server ASF JIRA serverId 5aa69414-a9e9-3523-82ec-879b028fb15b key HDFS-7240

• A detailed discussion and work on how HDSL can be used in HDFS is tracked in Building HDFS on top of new storage layer
• A detailed discussion of Ozone file system and design docs can be found here. 
• A detailed and work items for the security of  Hadoop Distributed Storage Layer is tracked in this JIRA

• The documentation is part of the source code, but you can check directly from github: https://github.com/apache/hadoop/tree/HDFS-7240/hadoop-hdfs-project/hadoop-hdfs/src/site/markdown See the markdown files with Ozone prefix (Or you can generate a new site from the feature branch)
