In Place Upgrades
Facing budget constraints for new infrastructure upgrades? This method enables you to upgrade your cluster while conserving resources within a planned maintenance window.
Advantages
No additional infrastructure investment required.
No data movement concerns.
Parallel installation alongside existing Hadoop binaries.
Step-by-step guidance provided by Runbook(s).
Plan for an 8-hour downtime window.
Allocate 4 hours for rollback procedures.
Ensure job alignment or modification ahead of time if reliant on legacy jars.
Preparation
Sidecar Upgrades
Upgrade smoothly with minimal maintenance and ample time to validate ODP's performance.
Advantages
Minimal upgrade downtime (< 1hr).
Rapid rollback capability (< 1hr).
Gradual job deployment for streamlined implementation.
Ample bandwidth for benchmarking and application validation.
Plan for parallel hosting or infrastructure costs until cutover.
Prepare for data movement or forking ingestion pipelines to the new cluster.
Preparation
Forklift Upgrades
Establish a parallel ODP cluster either on-premises or in the cloud and execute the migration.
Advantages
Minimal upgrade downtime required (< 1hr).
Quick rollback capability (< 1hr).
One-time data and job movement could be performed in phases as well.
Ideal for hardware refresh/ infra change motions.
Allocate resources for running a similarly sized cluster.
Prepare for data ingestion pipeline forking or data copying from the old to the new cluster.
