## Data Catalog
In the `[metadata]` section, Hue is supporting Cloudera Navigator and soon Apache Atlas ([HUE-8749](https://issues.cloudera.org/browse/HUE-8749)) in order to enrich the [data catalog](/user/browsers/).
## Spark
The `[spark]` section details how to point to [Livy](https://livy.incubator.apache.org/) in order to execute interactive Spark snippets in Scala or Python.
[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.
To configure Hue as a default proxy user, add the following properties to /etc/oozie/conf/oozie-site.xml:
oozie.service.ProxyUserService.proxyuser.hue.hosts
*
oozie.service.ProxyUserService.proxyuser.hue.groups
*
## YARN Cluster
Hue supports one or two Yarn clusters (two for HA). These clusters should be defined
under the `[[[default]]]` and `[[[ha]]]` sub-sections.
# Configuration for YARN (MR2)
