Before you connect to the Pentaho Server, set the connection path to the metastore, which is where these types of connections are stored.
Navigate to the pentaho-server/pentaho-solutions/system/kettle/plugins/pentaho-big-data-plugin directory and open the plugin.properties file with any text editor.
Locate the hadoop.configurations.path property and set the value to the metastore directory. For example, /home/devuser/.pentaho/metastore.
