Abstract
A method for improving fault tolerance of MapReduce computing systems processing extremely large data sets employs a custom mapper script that outputs the results to the shuffle and reduce processes. The Reducer writes its results into multiple files that are then compressed. The resulting files are processed by a map-only Reducer job that aggregates and reduces the results of a single file into a single output. The non-block compression prevents the file from being split across multiple mappers. The job can recover if a single mapper fails without requiring that each Map node be rerun, thus improving fault tolerance.
