The Local Ambari Managed Cluster Configuration option is enabled on the Ambari Admin page if you are managing a cluster with Ambari. When enabled, you can choose this option and Ambari will automatically configure the view based on how the cluster is configured.

When you configure the view using the Local option, the Files View communicates with HDFS based on the fs.defaultFS property (for example: hdfs://namenode:8020). The View also determines whether NameNode HA is configured and adjusts accordingly.
