The Truth About MapReduce Performance on SSDs

Categories: Hadoop Hardware MapReduce Performance

Cost-per-performance, not cost-per-capacity, turns out to be the better metric for evaluating the true value of SSDs.

In the Big Data ecosystem, solid-state drives (SSDs) are increasingly considered a viable, higher-performance alternative to rotational hard-disk drives (HDDs). However, few results from actual testing are available to the public.

Recently, Cloudera engineers did such a study based on a combination of SSDs and HDDs, with the goal of determining to what extent SSDs accelerate different MapReduce workloads,
