Feature Description

You can export the software configuration parameters of existing clusters in the EMR Console, so that when you create clusters in the future, you can quickly reuse these parameters for software configuration.

• Currently, software configuration is supported only for the following files:
• HDFS: core-site.xml, hdfs-site.xml, hadoop-env.sh, log4j.properties
• YARN: yarn-site.xml, mapred-site.xml, fair-scheduler.xml, capacity-scheduler.xml, yarn-env.sh, mapred-env.sh
• Hive: hive-site.xml, hive-env.sh, hive-log4j2.properties

Directions

1. Log in to the EMR Console and enter the cluster list page.
2. In the Manage column of the cluster to be exported, select More > Export Software Configuration.
   
3. Select the files to be exported and click Export Configuration to download the software configuration files.
