* An application is any Amazon or third-party software that you can add

* 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,
