Amazon Elastic MapReduce
API Reference (API Version 2009-03-31)


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 Using 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 cluster using MapR M3 or M5 Edition, respectively.


In Amazon EMR releases 4.x and later, the only accepted parameter is the application name. To pass arguments to applications, you supply a configuration for each application.



This option is for advanced users only. This is meta information about third-party applications that third-party vendors use for testing purposes.
