Context-smart Hadoop connections:
When defining this connection, you can contextualize the connection parameters using values from different Hadoop environments such as from a test and a production environments, in order to adjust the connection and the Jobs using the connection to the proper environments at runtime by only one click.
The advanced Spark properties can be centralized in the Hadoop connection wizard for reuse in Spark Jobs.
Retrieving Hadoop configuration via Jobserver:
If your local machine does not have access permissions to your Ambari or Cloudera manager, you can select a "Retrieve by Jobserver" check box and select your Jobserver to use this Jobserver to fetch the configurations from Cloudera Manager or Ambari.
