Currently Mapr doesn't have a way to set or acquire properties from the UI
To get the properties, on the server, navigate to /opt/mapr/hadoop/hadoop-2.x.x/etc/hadoop/yarn-site.xml. Here you can search for the properties.

Downloading the Properties

In Ambari and Cloudera there is also an option to "Download Client Configs". This can be found under the Actions tab of each service.
