[spark] # Host address of the Livy Server. ## livy_server_host=localhost # Port of the Livy Server. ## livy_server_port=8998 ## Kafka The configuration is in `[kafka]` but the service is still experiemental. ## Oozie In oder to schedule workflows, the `[liboozie]` section of the configuration file: [liboozie] oozie_url=http://oozie-server.com:11000/oozie Make sure that the [Share Lib](https://oozie.apache.org/docs/5.1.0/DG_QuickStart.html#Oozie_Share_Lib_Installation) is installed.
