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.
- Different departments or users can use different resource queues. This facilitates resource isolation.
- Resource queues are elastic, which improves the use efficiency of clusters.
Currently, you can use Capacity Scheduler or Fair Scheduler to manage E-MapReduce cluster resources.
