  • Cloudera Manager offers configurations and tools to optimize the usage of Tez as an execution engine for big data workloads, particularly when using Hive.
  • The Tez CM-UI in Cloudera Manager allows for fine-tuning of Tez configurations to meet specific workload requirements, including adjusting Tez container sizes, memory settings, and parallelism levels.
  • These Tez configurations can be applied cluster-wide, specifically for Hive.
  • Please verify that the HIVE and Hive_ON_TEZ services are active and functioning properly.
  • Similarly, the Core configuration applies to the entire cluster and provides an interface to change configurations cluster-wide.
  • Ensure that all services are running smoothly. If any particular service appears as red, investigate the individual service logs for further troubleshooting.
