Apache Ozone is a scalable, redundant, distributed object store for Hadoop and cloud-native environments, supporting billions of objects with strong consistency via Raft. It offers S3-compatible and Hadoop FileSystem APIs, replication or erasure coding, Kerberos/Ranger security, and deploys well on Kubernetes and YARN.
Use cases
- build a cost-effective S3-compatible object store on my own hardware
- replace HDFS for a petabyte-scale data lake
- store Iceberg table data and metadata for a lakehouse
- backend storage for Spark, Hive, Flink, or Impala workloads
- run a distributed storage cluster on Kubernetes
- store checkpoints and savepoints for Flink streaming jobs
- consolidate multiple HDFS clusters into one storage system
When to choose
- you need S3-compatible storage at petabyte scale with strong consistency
- you are outgrowing HDFS NameNode scalability limits
- you want a lakehouse backend with atomic rename for Iceberg commits
- you need Kerberos, Ranger, ACLs, and encryption in a storage layer
When to avoid
- you just need simple blob storage for a small app - MinIO or cloud object stores are simpler
- you need a POSIX network filesystem for general-purpose workloads
- your team has no capacity to operate a distributed Java storage cluster
