Incorporate MATLAB Map and Reduce Functions into a Hadoop MapReduce Job

Create a deployable archive of MATLAB® map and reduce functions, and incorporate it into a Hadoop® mapreduce job

To incorporate MATLAB map and reduce functions into a Hadoop mapreduce job, you create a deployable archive from the map and reduce functions and pass the archive as a payload argument to a job submitted to the Hadoop cluster. A deployable archive contains a:

  • mapper function written in MATLAB.

  • reducer function written in MATLAB.

  • MAT-file containing a datastore that describes the structure of the data and variables to be analyzed.

  • Hadoop settings file that identifies the map and reduce functions, the type of data being analyzed, and other configuration details.
