MRUnit support in HDP distribution

  • #27110

    Does anyone know if the HDP distribution has the necessary jar files that support MRUnit for unit testing Map/Reduce programs? I imported all the jar files from the Sandbox VM into my Eclipse project and was trying to create a MapDriver and ReduceDriver (MRUnit classes) and could not find them in the distribution. Do I have to manually install MRUnit jars into my eclipse project to create MRUnit code?

    Hi Krishna,

    Currently MRUnit is not supplied in the HDP distribution. So it does need to be downloaded manually.



    I downloaded the latest version of MRUnit onto my Eclipse development environment and was able to successfully run junit tests on my mapper, reducer and job locally.



    Hi Krishna,

    Thanks for letting us know that you have MRUnit working now.
