Configuration options for Spark to work with o3fs

After setting up o3fs, you can make configuration updates specific to components such as Spark to ensure that they work with Ozone.

To run Spark jobs with o3fs on a secure Kerberos-enabled cluster, ensure that you assign a valid URI by setting the value of the Spark Client Advanced Configuration Snippet (Safety Valve) property for the spark.conf or the spark-defaults.conf file through the Cloudera Manager web UI.
