The cluster resource management feature of E-MapReduce is ideal for scenarios that involve large-scale clusters with many tenants. Currently, you can only manage resources of E-MapReduce Hadoop clusters.
Background
The cluster resource management feature provides the following benefits:
- Different departments or users can use different resource queues. This facilitates resource isolation.
- Resource queues are elastic, which improves the use efficiency of clusters.
Resource management
Currently, you can use Capacity Scheduler or Fair Scheduler to manage E-MapReduce cluster resources.
- Capacity Scheduler: For more information, see Use Capacity Scheduler.
- Fair Scheduler: For more information, see Use Fair Scheduler.
Note You can also visit the official websites of Capacity Scheduler and Fair Scheduler to learn more about the components.
