This section describes installing CDAP on Amazon EMR clusters using the Amazon EMR "Run If" Bootstrap Action to:

• Install necessary EMR components;

• Restrict CDAP installation to the EMR master node;

• Download, install, and automatically configure CDAP for EMR; and

• Run all services as the 'cdap' user

Information on Amazon EMR is available online.

CDAP 6.2 is compatible with Amazon EMR 4.6.0 through 5.3.1.
