Problem

A regulated banking environment ran 5PiB of big data on a 300-node Cloudera Hadoop cluster that had to stay secure and highly available while routine operations consumed most of the team.

My role

Operated the 300-node Cloudera Hadoop cluster: secured it with Kerberos, TLS, and HashiCorp Vault dynamic secrets, tuned performance, and automated routine operations.

What shipped

  • +300-node Cloudera Hadoop cluster operated in production
  • +Kerberos, TLS, and Vault dynamic secrets across the cluster
  • +70% of routine operations automated
  • +25% improvement in critical task processing time through tuning

Outcome

  • →5PiB of banking big data managed on a secured cluster
  • →70% of routine operations automated
