Introduction to Workload Manager
Workload Manager is a tool that provides insights to help you gain in-depth understanding of the workloads you send to clusters managed by Cloudera Manager. In addition, it provides information that can be used for troubleshooting failed jobs and optimizing slow jobs that run on those clusters. After a job ends, information about job execution is sent to Workload Manager with the Telemetry Publisher, a role in the Cloudera Manager Management Service.
Workload Manager uses the information to display metrics about the performance of a job. Additionally, Workload Manager compares the current run of a job to previous runs of the same job by creating baselines. You can use the knowledge gained from this information to identify and address abnormal or degraded performance or potential performance improvements.
The Burst to Cloud functionality of Workload Manager utilizes Replication Manager and Data Warehouse to help you refine the parameters of your migration. This all done seamlessly within the Burst to Cloud wizard. The sections below walk you through the burst to cloud process, step by step.
