Goal
I would like to understand how Datameer picks up EMR cluster settings, when an administrator configures an EMR cluster name.
Learn
Once an Elastic Map Reduce(EMR) cluster name is specified, Datameer requests all required details from the AWS EMR service using the AWS SDK. Specifically, Datameer calls the ListClusters API call to get the master public DNS name, which is then used to configure the NameNode and the Resource Manager addresses.
