But, i t can be configured to schedule with both memory… Continue reading What is a Fair Scheduler in Hadoop?
What is a Capacity Scheduler in Hadoop?
Capacity Scheduler is a pluggable scheduler for Hadoop which allows for multiple-tenants to securely share a large cluster such that their applications are allocated resources in a timely manner under constraints of allocated capacities. Before the onset of Big Data and Hadoop, every organization had their own set of resources that had sufficient capacity to meet the… Continue reading What is a Capacity Scheduler in Hadoop?
