> Key: AMBARI-13901
> URL: https://issues.apache.org/jira/browse/AMBARI-13901
> Project: Ambari
> Issue Type: Bug
> Components: ambari-web
> Affects Versions: 2.1.0
> Reporter: Nathan Falk
> Fix For: trunk
>
>
> This defect is cloned from AMBARI-12851. Here is the original description:
> Hadoop Env configuration defined at the stack level is managed only if HDFS
> service is slected as part of the deployment. If HDFS is disabled and any
> alternate FS includes hadoop-env in the stack, the configuration should be
> understood by the Ambari code and corresponding hadoop-env.sh should be
> created properly on the hadoop/ambari agent machines.
> I do not believe that the issue has been fully addressed by AMBARI-12837.
> If a filesystem service is replacing HDFS, then it has to manage the
> core-site and hadoop-env configurations, and possibly hdfs-site as well. Many
> of these properties are defined in site_properties.js, but are defined as
> having a 'serviceName' of 'HDFS'. When it comes time for Ambari to display
> these properties in the UI, they get left out. This is true both on the
> customize services page of the installation wizard and on the Configs tab for
> the HCFS service.
> On installation, anything that the HCFS service has defined in the stack in
> core-site.xml, hdfs-site.xml or hadoop-env.xml does get saved to the
> database, even if some of the properties do not appear on the Customize
> Services page.
> However, if the admin tries to change any properties later (for example, the
> hadoop-env.sh content), then only those properties which are displayed by the
> UI, which are those properties that are NOT defined in site_properties.js,
> are saved.
> The issue seems to be in these areas of the code, all in
> ambari-web/app/utils/config.js:
> mergePredefinedWithSaved
> mergePredefinedWithLoaded
> serviceConfigUiAttributes
> All 3 of these functions will set 'serviceName' in the serviceConfigObj to
> the serviceName from the pre-defined config properties in configsPropertyDef.
