 package com.amazonaws.services.elasticmapreduce.model;
 

An application is any Amazon or third-party software that you can add to the cluster. This structure contains a list of strings that indicates the software to use with the cluster and accepts a user argument list. Amazon EMR accepts and forwards the argument list to the corresponding installation script as bootstrap action argument. For more information, see Launch a Job Flow on the MapR Distribution for Hadoop . Currently supported values are:

  • "mapr-m3" - launch the job flow using MapR M3 Edition.
  • "mapr-m5" - launch the job flow using MapR M5 Edition.
  • "mapr" with the user arguments specifying "--edition,m3" or "--edition,m5" - launch the job flow using MapR M3 or M5 Edition, respectively.
