*
* 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.
*
*
*
* In Amazon EMR releases 4.0 and greater, the only accepted parameter is the
* application name. To pass arguments to applications, you supply a
* configuration for each application.
