Perform these steps to reconfigure the Hadoop cluster before you configure SAS Data Loader (Trial Edition).

Note: The following steps are required only if you are using Cloudera Manager with Cloudera Quickstart VM.

6. Select the hdfs (Service-Wide) check box in the right-hand pane to activate the configuration option.
   
   
7. Click Save Changes.
   
   NOTE: Saving the changes does not immediately reconfigure the cluster. However, after saving the changes, your current cluster configuration is now considered “stale.” You must continue with the following steps to reconfigure the cluster.

   NOTE: It may be 30 seconds or more before the refresh completes.
