> Load 'final' attribute of service config-type files into StackServiceResponse
> -----------------------------------------------------------------------------
>
> Key: AMBARI-6329
> URL: https://issues.apache.org/jira/browse/AMBARI-6329
> Project: Ambari
> Issue Type: Task
> Components: client
> Affects Versions: 1.7.0
> Reporter: Srimanth Gunturi
> Assignee: Srimanth Gunturi
> Fix For: 1.7.0
>
>
> Hadoop stacks in Ambari have services defined in
> {{/ambari/ambari-server/src/main/resources/stacks/<stack-name>/<stack-version>/services/<service-name>}}.
> Each service defines its configurations in
> {{configurations/<config-type.xml>}} files. Each of these files must indicate
> whether they support 'final' flag in their bodies by defining
> {{supports_final="true|false"}} attribute in the root {{configuration}}
> element.
> Generally as a rule, any config-type file with below names should have
> {{supports_final="false"}}
> * global.xml
> * *-conf.xml
> * *-log4j.xml
> * *-properties.xml
> {{supports_final="true"}} should be set for files with following names
> * *-site.xml
> * *-policy.xml
> Once config-type files have supports 'final' flag as shown below, it should
> be loaded on startup.
> {code}
> <configuration supports_final="true"
> xmlns:xi="http://www.w3.org/2001/XInclude";>
> <property>
> <name>io.file.buffer.size</name>
> <value>131072</value>
> <description>The size of buffer for use ....</description>
> </property>
> ...
> </configuration>
> {code}
> When Ambari loads the stack model into _AmbariMetaInfo_, this information
> should be loaded into the
> _org.apache.ambari.server.state.ServiceInfo#configTypes_ property. The
> property's type should change from _List<String>_ to _Map<String,
> Map<String, Map<String, String>>>_ .
> {code}
> "config_types": {
> "core-site": {
> "supports": {
> "final": "true"
> }
> },
> "global": {
> "supports": {
> "final": "false"
> }
> },
> }
> {code}
> Testcases should be provided to verify the model is getting loaded properly
> (missing attribute, incorrect value, etc.). If _supports_final_ attribute is
> not provided, the value of false should be assumed.
