Get client configurations
Starting with ADH 4.0.0, you can export client configurations of the services currently installed in an ADH cluster. The exported configurations can be used, for example, to configure client software that connects to ADH, or to configure the services of another ADH cluster.
Overview
The configuration export functionality is embedded into the Core configuration service. Particularly, the service has the Export client configurations action, which collects configurations of the currently installed services, archives them, and makes them available for download via an Nginx endpoint.

NOTE
The Configuration server and Hive Tez components must not be mapped on the same ADH host.
|
The configurations are exported as separate .tar.gz archives for each service. The list of exported services and files is presented below.
Exported configuration files
The Export client configurations action exports configurations for the following services.
| Service | Configuration file(s) |
|---|---|

core-site.xml ssl-client.xml log4j.properties.xml |
HDFS |
hdfs-site.xml log4j.properties.xml |
YARN |
yarn-env.sh yarn-site.xml mapred-site.xml |
Hive |
hive-site.xml hive-env.sh beeline-hs2-connection.xml beeline-log4j2.properties hive-log4j2.properties hive-log4j.properties hive-metastore-env.sh hive-server2-env.sh tez-site.xml |
Solr |

Configuration export example
The following steps show how to export the configurations of an ADH cluster:
-
In ADCM, go to Clusters → <cluster_name> → Services → Core configuration.
-
Run the Export client configurations service action.
-
Go to the Core configuration → Info page and follow the Configuration server web interface link (http://<configuration_server_host>:9998). The web page displays a list of tar.gz archives with configurations for each service. For example:
../ all_configs.tar.gz 13-Aug-2025 16:06 7948 core.tar.gz 13-Aug-2025 16:06 4632 hdfs.tar.gz 13-Aug-2025 16:06 1494 yarn.tar.gz 13-Aug-2025 16:06 2486
