Update Connections

You might need to update connections based on the version you are upgrading from.

Consider the following types of updates that you might need to make:

Configure the Hadoop connection.: Configure the Hadoop connection to incorporate properties from the hadoopEnv.properties file.
Replace connections.: If you chose the option to create connections when you ran the
Cluster Configuration
wizard, you need to replace connections in mappings with the new connections.
Complete connection upgrades.: If you did not create connections when you created the cluster configuration, you need to update the connections.
