Scheduling in Hadoop An introduction to the pluggable scheduler framework,
by M. Tim Jones, Consultant Engineer, Independent author
Summary:
Hadoop implements the ability for pluggable schedulers that assign resources to jobs. However, as we know from traditional scheduling, not all algorithms are the same, and efficiency is workload and cluster dependent. Get to know Hadoop scheduling, and explore two of the algorithms available today: fair scheduling and capacity scheduling. Also, learn how these algorithms are tuned and in what scenarios they’re relevant.
Not all topic maps are going to need Hadoop but enough will to make knowing the internals of Hadoop a real plus!
