SkewTune in action
YongChul Kwon, Magdalena Bałazińska, Bill Howe, Jerome Rolia · Proceedings of the VLDB Endowment · 2012
We demonstrate SkewTune, a system that automatically mitigates skew in user-defined MapReduce programs and is a drop-in replacement for Hadoop. The demonstration has two parts. First, we demonstrate how SkewTune mitigates skew in real MapReduce applications at runtime by running a real application in a public cloud. Second, through an interactive graphical interface, we demonstrate the details of the skew mitigation process using both real and synthetic workloads that represent various skew configurations.
