Testing MapReduce programs: A systematic mapping study

Jesús Morán, Claudio Riva, Javier Tuya
2018 Journal of Software: Evolution and Process  
The principal reasons for testing the programs are performance issues, potential failures, issues related to the data, or to satisfy the agreements with efficient resources.  ...  Firstly, two computers analyze the data, but one computer fails and this analysis is re-executed in a third computer.  ...  In this case there could be at least two issues: (1) performance problems if these two years are analyzed in the same computer, and (2) memory leaks or resource issues due to the high quantity of data  ...
