.Code Block mkdir -p configuration cd configuration
Create the
test-config.xml
file. For example:Code Block <?xml version="1.0"?> <?xml-stylesheet type="text/xsl" href="configuration.xsl"?> <configuration> <property> <name>some.test.property</name> <value>this.is.the.default.value</value> <description>This is a test description.</description> </property> <property> <name>another.test.property</name> <value>5</value> <description>This is a second test description.</description> </property> </configuration>
There is an optional setting "configuration-dir". Custom services should either not include the setting or should leave it as the default value "configuration".
Code Block <configuration-dir>configuration</configuration-dir>
- Configuration dependencies can be included in the metainfo.xml in the a "
configuration-dependencies
" section. This section can be added to the service as a whole or a particular component. One of the implications of this dependency is that whenever the config-type is updated, Ambari automatically marks the component or service as requiring restart.Code Block <configuration-dependencies> <config-type>core-site</config-type> <config-type>hdfs-site</config-type> </configuration-dependencies>
