Hadoop Workload Analysis

Contact: Kai Ren, Garth Gibson

We have analyzed Hadoop workloads from three different research clusters from a user-centric perspective. The goal is to better understand data scientists' use of the system and how well the use of the system matches its design.

Overall, our analysis suggests that Hadoop usage is still in its adolescence. We do see good use of Hadoop: all workloads are dominated by data transformations that Hadoop handles well; users leverage Hadoop's ability to process massive-scale datasets; customizations are used in a visible fraction of jobs for correctness or performance reasons. However, we also find uses that go beyond what Hadoop has been designed to handle:

In summary, we find that users today make good use of their Hadoop clusters, but there is also significant room for improvement in how users interact with them:
