Apache Hadoop is an open-source software framework for storage and large-scale processing of datasets on clusters of commodity hardware. Explore resource management through scheduling, the Fair Scheduler tool, and how to plan for scaling.

WHAT YOU WILL LEARN

  • recall how to set the maximum and minimum memory allocations per container
    describe how the fair scheduling method allows all applications to get equal amounts of resource time
    describe the primary algorithm and the configuration files for the fair scheduler
    describe the default behavior of the fair scheduler methods
    monitor the behavior of Fair Share
    describe the policy for single resource fairness
    describe how resources are distributed over the total capacity
    identify different configuration options for single resource fairness
  • configure single resource fairness
    describe the minimum share function of the fair scheduler
    configure minimum share on the fair scheduler
    describe the preemption functions of the fair scheduler
    configure preemption for the fair scheduler
    describe dominant resource fairness
    write service levels for performance
    use the fail scheduler with multiple users
