Overview

Note:

When making an API call, you may pass Application data as a hash:

{
  name: "String",
  version: "String",
  args: ["String"],
  additional_info: {
    "String" => "String",
  },
}

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.

<note markdown=“1”> 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.
