Customizing configuration profile files

Customize options for files that comprise an LCM configuration profile.

Define configuration profiles to specify how DataStax Enterprise (DSE) will be configured. A configuration profile enforces uniform configuration at the cluster, datacenter, or node level.

Each configuration profile is specific to a supported version of DSE. A configuration profile is composed of multiple configuration files for configuring features of DSE clusters.

Configuration profiles allow customizing settings for the following DSE configuration files.


The location of the dse.yaml file depends on the type of installation:
Package installations /etc/dse/dse.yaml
Tarball installations installation_location/resources/dse/conf/dse.yaml

The location of the file depends on the type of installation:
Package installations /etc/dse/cassandra/
Tarball installations installation_location/resources/cassandra/conf/


The location of the cassandra.yaml file depends on the type of installation:
Package installations /etc/dse/cassandra/cassandra.yaml
Tarball installations installation_location/resources/cassandra/conf/cassandra.yaml

  5. Run a configuration job to push configuration profile updates and apply them at the cluster, datacenter, or node level.

Configuration profile files

Cassandra section

Note: When you add a configuration profile, DSE authentication is enabled by default for all supported versions of DSE. DSE Authenticator is enabled in dse.yaml for DSE version 5.0 and later. For more information, see Managing DSE Security using LCM.

Every configuration option in cassandra.yaml and dse.yaml is editable, while other configuration files use a template system that exposes only frequently used settings. Contact DataStax Support to request additional configuration options.

Spark section

  • spark-alwayson-sql.conf
  • logback-sparkR.xml
  • logback-spark.xml
  • spark-defaults.conf
  • logback-spark-executor.xml
  • logback-spark-server.xml
  • hive-site.xml
  • spark-daemon-defaults.conf

For more information about Spark, see Configuring Spark and Configuring Spark logging options.

Lifecycle Manager section

  • Package Proxy: Accelerate package downloads or isolate DSE clusters offline from the internet.
  • Java Setup: Automatically manages JRE installs and JCE Policy files.
Note: A configuration file explicitly not managed at this time by Lifecycle Manager is, which is used for configuring commit log archive and PIT restore for the Backup Service. This file is managed instead from within the Backup Service.
