      A list of strings that indicates third-party software to use with the job flow that accepts a user argument list. EMR accepts and forwards the argument list to the corresponding installation script as bootstrap action arguments. For more information, see Launch a Job Flow on the MapR Distribution for Hadoop. Currently supported values are:
      
      "mapr-m3" - launch the cluster using MapR M3 Edition.
      
      "mapr-m5" - launch the cluster 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.
      
      "mapr-m7" - launch the cluster using MapR M7 Edition.
      
      "hunk" - launch the cluster with the Hunk Big Data Analtics Platform.
