Configuration File for Creating Deployable Archive Using the mcc Command

When creating a deployable archive using the mcc command, you must create a text file containing the following information:

Parameter Type	Description
mw.ds.out.type	Output type of data from Hadoop® mapreduce job The options are: keyvalue tabulartext
mw.mapper	Name of MATLAB® map function
mw.reducer	Name of MATLAB reduce function
mw.ds.in.format	Name of MAT-file containing a datastore object representing the format of the data to be processed. In most cases, you will start off by working on a small sample dataset residing on a local machine that is representative of the actual dataset on the cluster. This sample dataset has the same structure and variables as the actual dataset on the cluster. By creating a datastore object to the dataset residing on your local machine you are taking a snapshot of that structure. By having access to this datastore object, a Hadoop job executing on the cluster will know how to access and process the actual dataset residing on HDFS™.
mw.ds.in.type	Input type of data to Hadoop mapreduce job The options are: keyvalue tabulartext
mw.ds.in.fullfile	Default value is false

Sample Configuration File

config.txt

mw.ds.out.type = keyvalue
mw.mapper = maxArrivalDelayMapper
mw.reducer = maxArrivalDelayReducer
mw.ds.in.format = infoAboutDataset.mat
mw.ds.in.type = tabulartext
