Exit Cloudera. Modernize Hadoop. Without betting the business.

Bifrost is Ilum's purpose-built Hadoop and Cloudera CDP migration toolkit. It is a command-line migration framework that automates discovery, configuration translation, data movement, validation, and rollback, taking enterprises through the full lifecycle of Hadoop modernization with auditable, reproducible, go/no-go gated steps.

Yes. For an in-place license exit (Cloudera CDP to open-source Hadoop), Bifrost performs a stop-and-swap cutover within a planned weekend window, typically around 6-8 hours of overnight downtime to swap packages and upgrade HDFS, followed by automated validation and benchmarking before Monday. Larger 100+ node clusters can instead use the shrink-and-grow strategy, which keeps HDFS online throughout and migrates nodes in batches over a few days.

Yes. During an in-place migration, data directories on source nodes are never touched. Every step is reversible until an explicit, final step: a multi-day soak period keeps a full rollback option open (roughly a 4-hour revert), and row-count plus value-level data-diff checks must pass before any migrated table is treated as authoritative. Any detected mismatch aborts the migration.

Bifrost maps the full Hadoop and Cloudera stack to modern equivalents: HDFS to S3A-compatible object storage, YARN to Spark on Kubernetes, the Hive Metastore to an Apache Iceberg REST catalog, Hive and Impala to Trino, Oozie to Apache Airflow, Ranger to Open Policy Agent, HBase to Cassandra or ScyllaDB, and Atlas to OpenMetadata. It is explicit about automation ceilings, what it fully automates versus what needs manual follow-up.

No. The Classic path replatforms Cloudera CDP onto open-source Apache Hadoop in place, eliminating licensing while preserving your existing architecture and bare-metal footprint. You can modernize to Ilum on Kubernetes later with the Modernize path, or do both at once with the Direct path.

No, not for the Classic license exit. Bifrost preserves the cluster architecture and creates compatibility symlinks, so Spark and Hive jobs, Oozie workflows, SQL, and BI dashboards keep running unchanged on open-source Hadoop. When you later modernize to Kubernetes, a dual-read bridge and Trino table redirection keep consumers working while storage and orchestration move underneath, so modernization such as Oozie to Airflow happens progressively rather than as a forced big-bang rewrite.

Organizations typically save $500K-2M annually by eliminating Cloudera licensing fees, depending on deployment size. Combined with reduced support costs and avoided hardware refresh cycles, total infrastructure cost savings commonly range from 60-75% of current Cloudera infrastructure expenses.

It depends on the path. A Classic in-place license exit cuts over in a single weekend per cluster, with a 4 to 6 month program for a large multi-cluster estate. Modernize and Direct programs, which move you to a Kubernetes lakehouse, typically run 2 to 5 months and are fully phased, so production keeps running throughout.

Bifrost fits Cloudera CDP 7.x and open-source Hadoop estates that mix HDFS, YARN, Hive, Oozie, and Ranger. If you need to exit Cloudera licensing fast while staying on bare metal, start with Classic. If you are ready for Kubernetes, use Modernize or Direct. A migration assessment confirms the right path and surfaces the automation ceiling for your specific workloads.

No. The destination uses open formats and open-source components: Apache Iceberg tables, Parquet and ORC files, S3-compatible APIs, and open catalogs. The exit path is not obstructed by proprietary data formats or catalog implementations, so you keep the option to leave and run the open-source components directly.

Start with a migration assessment. Bifrost runs an automated discovery of your estate and produces a scored migration plan with wave assignments, a total cost of ownership projection, and an automation-ceiling report, along with a recommended path.
