Hadoop services that ensure zero-disruption migrations

Stabilize

Hadoop ecosystem health assessment

We assess your full Hadoop environment and catalog every workload, pipeline, and dependency. You get a benchmarked baseline with a prioritized remediation plan for unsupported CDH or HDP clusters.

Optimize

Performance tuning and governance hardening

We optimize HDFS storage, tune YARN resource allocation, and more—making your current investment work harder while establishing the governance baseline your migration depends on.

Migrate and modernize

Platform migration and pipeline modernization

Pythian migrates Hadoop workloads to Databricks, BigQuery, and Snowflake. Your modernized platform unlocks analytics and capabilities that weren't feasible on Hadoop.

How we work with you

Plan your data modernization pathway

We assess cluster health, performance, and security posture. For unsupported distributions, we stabilize mission-critical workloads while planning the path forward.

Catalog your data workloads

We catalog every workload, pipeline, and policy, then map the dependencies—the critical prerequisite most programs miss.

Strategize your data roadmap

We recommend the right path—CDP upgrade, cloud-native exit, or hybrid—based on workload analysis and ROI modeling, with phased milestones for quick wins.

Data migration without disruption

We migrate data, code, workflows, security, and metadata to their targets. Dual-run validation ensures zero disruption.

Continued data ecosystem support

We deliver modern dashboards, self-service analytics, and AI-ready pipelines—plus 24/7 support so your team can focus on extracting value.

Modernizing big data infrastructure from Hadoop for a tier-1 financial institution

From unsupported Hadoop to governed Databricks Lakehouse—55% cost reduction and production AI in under a year.

A global financial institution with $200B+ in assets under management ran regulatory reporting, fraud detection, and risk analytics on an aging, unsupported Hadoop cluster. Pythian inventoried the 25+ component ecosystem, executed a phased migration, and delivered $1.3M in annual savings, 10x query performance, and a production-ready AI foundation.

Hadoop consulting services frequently asked questions (FAQ)

How do you handle security and compliance during a Hadoop migration, especially for regulated industries?

Security is built into every phase of our migration process. We start with a comprehensive security vulnerability assessment of your existing cluster—critical for organizations running unsupported CDH or HDP distributions. During migration, we remap your Kerberos authentication and Apache Ranger fine-grained access controls to cloud-native IAM frameworks (AWS IAM, GCP IAM, Azure AD), preserving the access policies that regulated industries depend on. We also migrate your data governance metadata from Apache Atlas to modern platforms like Google Dataplex, Collibra, or Unity Catalog. Dual-run validation ensures no gaps in security coverage during the transition.

What kind of ROI can we expect from a Hadoop modernization?

The ROI from Hadoop modernization comes from multiple sources. Infrastructure cost savings are often the most immediate win—one customer eliminated nearly $500K per year in on-premises hardware and Cloudera licensing costs. Beyond cost reduction, organizations typically see 10x or greater query performance improvements over legacy Hive on MapReduce, dramatic reductions in operational complexity (from managing 20+ ecosystem components to a single managed platform), and the ability to enable self-service analytics and production AI capabilities that were impossible on the legacy cluster. The phased approach we recommend means you start seeing returns on high-value workloads early in the migration—not just at the end.

We have hundreds of Oozie workflows and custom MapReduce jobs. How much of the migration can be automated?

Automated conversion tools can typically handle 70–90 percent of standard HiveQL queries. However, the remaining queries—those with complex nested data types, custom SerDes, and Java UDFs—require manual refactoring by engineers who understand both the source and target platforms. MapReduce jobs and Pig scripts have no direct automated conversion path; they must be rewritten as Spark jobs, PySpark, or cloud-optimized SQL. Oozie workflow migration to Apache Airflow or Databricks Workflows is similarly labor-intensive because each DAG coordinates multiple interdependent Hive, Spark, MapReduce, and shell jobs. This is precisely where Pythian's deep Hadoop ecosystem expertise makes the difference—we've done this work across complex, multi-petabyte environments and know where the hidden dependencies live.

Should we upgrade to Cloudera CDP or exit to a cloud-native platform?

It depends on your workload characteristics, strategic direction, and budget. CDP is a strong choice for organizations that want to preserve their existing Hive tables, Spark jobs, and security models while gaining modern capabilities like Apache Iceberg support and hybrid cloud deployment. Cloud-native platforms like Databricks, BigQuery, or Snowflake are better suited for organizations ready to fully decouple from the Hadoop ecosystem and gain serverless scaling, modern BI integration, and AI-ready infrastructure. A third option—phased hybrid—lets you migrate high-value workloads to cloud-native platforms first while maintaining the Hadoop cluster for lower-priority batch jobs during the transition. Pythian provides vendor-neutral assessment based on workload analysis and ROI modeling, not vendor loyalty.
