What you get with this Offer
I will assess your Hadoop cluster configuration and deliver a detailed architecture review report covering HDFS storage utilisation, NameNode configuration, DataNode health, replication factor settings, YARN resource allocation, job scheduling configuration, security setup (Kerberos, Ranger, or Knox), and performance bottlenecks — with prioritised recommendations your cluster administrators can action. Hadoop clusters that are set up correctly for initial workloads frequently develop configuration drift as data volumes and job complexity grow, producing performance degradation that is misattributed to Hadoop's limitations rather than addressable configuration issues.
The report covers NameNode heap and GC configuration, HDFS block size and replication settings, YARN memory and vCore allocation per node, MapReduce or Tez configuration, security policy review, data skew issues in existing jobs, and storage tiering opportunities. Each finding is prioritised by impact with specific configuration changes recommended.
This service suits data engineering teams, organisations evaluating Hadoop ROI, and enterprises preparing for a cluster upgrade or migration to a cloud-based distribution (Cloudera, Hortonworks, or EMR).
