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.
