--- title: "Other services" date: 2019-03-13T18:28:09-07:00 draft: false weight: 4 --- ## 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) # ------------------------------------------------------------------------ [[yarn_clusters]] [[[default]]] resourcemanager_host=yarn-rm.com resourcemanager_api_url=http://yarn-rm.com:8088/ proxy_api_url=http://yarn-proxy.com:8088/ resourcemanager_port=8032 history_server_api_url=http://yarn-rhs-com:19888/ ## Oozie In the `[liboozie]` section of the configuration file, you should specify: [liboozie] oozie_url=http://oozie-server.com:11000/oozie ## Solr In the `[search]` section of the configuration file, you should specify: [search] # URL of the Solr Server solr_url=http://solr-server.com:8983/solr/ ## Spark The `[spark]` section details how to point to [https://livy.incubator.apache.org/](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 ## Catalog In the `[metadata]` section, Hue is supporting Cloudera Navigator data catalog and soon Apache Atlas ([HUE-8749](https://issues.cloudera.org/browse/HUE-8749)). ## Query Optimization In the `[metadata]` section, Hue is supporting Cloudera Navigator Optimiser and soon other services. The goal is to provide recommendation on how to write better queries and get risk alerts on dangerous operations. ## Kafka The configuration is in `[kafka]` but the service is still experiemental.
