In the [metadata] section, Hue is supporting Cloudera Navigator and soon Apache Atlas (HUE-8749) in order to enrich the data catalog.
The [spark] section details how to point to Livy 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
The configuration is in [kafka] but the service is still experiemental.
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 is installed.

<!-- Default proxyuser configuration for Hue -->
<property>
<name>oozie.service.ProxyUserService.proxyuser.hue.hosts</name>
<value>*</value>
</property>
<property>
<name>oozie.service.ProxyUserService.proxyuser.hue.groups</name>
