+ * A Dynamic MapReduce Scheduler for Heterogeneous Workloads 
+
+Abstract—MapReduce is an important programming model for building data centers containing ten of thousands of nodes. In a
+practical data center of that scale, it is a common case that I/Obound
+jobs and CPU-bound jobs, which demand different
+resources, run simultaneously in the same cluster. In the
+MapReduce framework, parallelization of these two kinds of job
+has not been concerned. In this paper, we give a new view of the
+MapReduce model, and classify the MapReduce workloads into
+three categories based on their CPU and I/O utilization. With
+workload classification, we design a new dynamic MapReduce
+workload predict mechanism, MR-Predict, which detects the
+workload type on the fly. We propose a Triple-Queue Scheduler
+based on the MR-Predict mechanism. The Triple-Queue
+scheduler could improve the usage of both CPU and disk I/O
+resources under heterogeneous workloads. And it could improve
+the Hadoop throughput by about 30% under heterogeneous
+workloads.
