HDP Administrator / Architect

Role Summary The HDP Administrator / Architect will provide deep technical expertise in administering and modernizing Hortonworks (HDP) and Cloudera environments as part of enterprise-scale data modernization initiatives powered by NexusOne . This role is responsible for ensuring operational stability, performance, and compliance of existing Hadoop environments, while architecting and supporting the transition toward open-source, cloud-native components (e.g., Spark, Iceberg, Trino, Ranger, DataHub).

This individual must possess hands-on depth in the full Hortonworks stack — from cluster management and security to performance tuning and metadata governance — serving as the technical bridge between legacy and modern data ecosystems.

Core Responsibilities

Administer, monitor, and optimize Hortonworks Data Platform (HDP) clusters, including HDFS, YARN, Hive, HBase, Oozie, Ranger, Atlas, and Ambari.

Perform environment maintenance and upgrades — patching, version management, capacity planning, and backup / recovery.

Ensure platform reliability, high availability, and adherence to enterprise security and compliance requirements.

Collaborate with Data Engineering and Platform Architecture teams to design migration strategies from HDP / Cloudera to modern open-source frameworks.

Lead the migration of data, metadata, and security policies from legacy components (e.g., Atlas / Ranger) to DataHub, Iceberg , and modern equivalents.

Conduct root-cause analysis and resolve complex performance or stability issues across distributed systems.

Implement and maintain Kerberos, LDAP / SSO integration, and role-based access control (RBAC) policies.

Document architecture, configurations, and operational runbooks for cluster management and decommissioning.

Train and mentor engineers in HDP administration, troubleshooting, and modernization best practices.

Must-Have Core Skills

Deep Hortonworks Expertise : Proven hands-on administration experience with HDP 2.x / 3.x , including HDFS, YARN, Hive, HBase, Oozie, Ranger, Atlas, Ambari, and Kerberos.

Cloudera Stack Knowledge : Understanding of Cloudera Manager and CDP transition paths.

Security & Governance : Expertise in configuring and managing Ranger, Atlas, Kerberos, LDAP / SSO , and encryption frameworks.

Performance Optimization : Skilled in resource tuning, query optimization, and capacity planning for large-scale clusters.

Automation & Infrastructure : Experience with Ansible, Terraform , or equivalent for provisioning and configuration management.

Monitoring & Observability : Hands-on with Grafana, Prometheus, Ambari Metrics , or equivalent platforms.

Scripting & OS : Strong Linux administration and scripting (Bash, Python).

Ideal Background

5–10 years of experience as an HDP or Cloudera Administrator supporting production-grade clusters at scale.

Deep operational experience with Hortonworks Data Platform (HDP) , including upgrades, troubleshooting, and tuning.

Prior involvement in data platform modernization or cloud migration programs .

Knowledge of emerging open-source frameworks (Spark, Trino, Iceberg, Ranger, DataHub).

Proven ability to collaborate across platform, security, and data teams to deliver mission-critical outcomes.

Success Criteria

Sustained platform stability and high availability throughout modernization.

Successful migration of data, metadata, and policies to NexusOne-aligned open-source components.

Zero major incidents or regressions during transition or decommissioning.

Clear documentation and knowledge transfer to engineering and operations teams.

Recognition as a subject-matter expert in Hortonworks administration and modernization best practices .
