What's New in Apache Ozone

Snapshot support in Ozone

Learn about different scenarios where you can use snapshots, the snapshot APIs that are available for use, and the snapshot architecture.

For more information, see Working with snapshots in Ozone.

Erasure Coding Enhancements

The Ozone Erasure Coding feature provides data durability and fault-tolerance along with reduced storage space and ensures data durability similar to Ratis THREE replication approach.

For more information, see Erasure Coding.

SCM Certificate Rotation

Configuring security and issuing certificates to Storage Container Managers (SCMs) along with Ozone Managers (OMs) and the DataNodes ensures secured communication in the Ozone cluster.

For more information, see Configuring security for Storage Container Managers in High Availability.

Master node decommissioning in Ozone

This feature helps you to decommission Ozone Manager (OM) and Storage Container Manager (SCM).

For more information, see Master node decommissioning in Ozone .

Recon Heat Map

You can access the heatmap feature as an administrator to read or view the most accessed volumes, buckets, and top 100 keys across Apache Ozone.

For more information, see Recon Heat Map.

Managing Ozone quota

The Ozone shell is the primary command line interface for managing the quota of volumes and buckets.

For more information, see Managing Ozone quota.

Ozone Knox Integration

Ozone and Knox are now integrated to work together.

For more information, see Ozone Knox integration.

Configuration options for Oozie to work with Ozone storage

Oozie supports Ozone storage along with HDFS.

Apache Ozone is a highly scalable next-gen object store available on the CDP Private Cloud Base cluster which enables you to optimize storage for big data workloads.

For more information, see Configuration options for Oozie to work with Ozone storage.

Ozone HttpFS support

Ozone now supports HttpFS Gateway. This allows Ozone to integrate with other tools through REST APIs.

For more information, see Ozone HttpFS support.

Configuration options for Impala to work with Ozone File System

Learn how Ozone can work with Impala.

You can use Impala to query data files that reside on Apache Ozone distributed storage, rather than in HDFS.

For more information, see Configuration options for Impala to work with Ozone File System.

Determining the threshold

Container Balancer balances the utilization of DataNodes in a cluster using the Threshold. You can now determine the threshold value before configuring the required parameters.

For more information, see Determining the threshold.

Volume and bucket management using ofs

This is a new improvement to the existing feature where you can now use _ in naming volume and bucket.

For more information, see Volume and bucket management using ofs.

Ozone volume scanner

The Ozone Volume Scanner feature enables to detect any disk failures on the DataNodes. Learn how you can configure the frequency of volume scans that can detect disk failures and how to handle volume failures.

For more information, see Ozone volume scanner.

Ozone OMDBInsights

The Ozone Manager Database Insights feature helps you view the container mismatch information, open keys, keys pending for deletion, and deleted container keys.

For more information, see Ozone OMDBInsights.
