Hi again,
My problem was some missing configuration properties on the .xml file of the
service definition.
The previous steps mentioned by Srimantha re enough to enhance service
configurations using the new theme framework.
Thanks again

Thanks Sgunturi,
It seems to me that following these steps should be correct:
- adding the themes directory, which includes the theme.json file, on my
stack service
- configuring themes directory on the service metainfo.xml
- Editing -env.xml and -site.xml files to include the <value-attributes> for
the required properties on the theme.json file
but I'm not able to see the new controls on the installation wizard for my
services. This approach iscurrently working just for HDFS, but failing with for
other services asHBASE or YARN.
I'm debugging the UI and hitting these errors:Error:
<DS.StateManager:ember22432>could not respond to event setAssociation in state
rootState.loading.Error: <DS.StateManager:ember6260>could not respond to event
didChangeData in staterootState.loaded.updated.uncommitted.
I'm doing something wrong? Not changes are required on ambari-web module?

Hello,
This is work in progress, but you should be able to define a theme for your
service and get enhanced configurations - with controls like Sliders, Combos,
Toggles, etc.
The trunk builds already have theme based enhanced-configs for HDFS, YARN,
MapReduce, Hive & HBase. These can be seen inside respective service folders of
the stack definitions -
https://github.com/apache/ambari/blob/trunk/ambari-server/src/main/resources/stacks/HDP/2.2/services/
Step 1) Define themes to use in metainfo.xml
https://github.com/apache/ambari/blob/trunk/ambari-server/src/main/resources/stacks/HDP/2.2/services/HDFS/metainfo.xml#L93
Step 2) Create theme JSON file in themes/ folder.
Theme should have 'configuration' object with properties 'layouts', 'placement'
and 'widgets'. 'Layouts' determines the tabs and sections within respective
tabs. It is the general layout of the configurations
'Placement' determines which configurations go into what sub-sections
'Widgets' determines which UI widgets to use for respective configs. Also, UI
specific metadata can be specified here (like what units the value should be
shown in - MB, GB, Days, etc.)
https://github.com/apache/ambari/blob/trunk/ambari-server/src/main/resources/stacks/HDP/2.2/services/HDFS/themes/theme.json
Step 3) Define non-UI metadata for configs
Configs which are shown via a theme need some non-UI metadata defined on them.
Things like <display-name>, and additional attributes about the value - like
<minimum>, <maximum>, <increment-step> etc.
https://github.com/apache/ambari/blob/trunk/ambari-server/src/main/resources/stacks/HDP/2.2/services/HBASE/configuration/hbase-site.xml#L198
This should allow you to see enhanced-configurations for your service.
Hoping that helps.
Regards,
Srimanth

Subject: Using theme framework on my own stack
Hi all,
Im trying to use thenew theme framework on my own stack. The goal is to add the
new lookand feel with slider controls in the configuration of myservices.
It seems to me that adding the themes directory,which includes the theme.json
file on my stack service , and configuring this directoryon the service
metainfo.xml should be correct,but I'm not able to see the slider controls on
the installationwizard. This approach is not working for HDFS, which is the
serviceI'm testing.
Do I need to add/modify something else on theambari-web module? Do I need to
provide some endpoint for thetheme?
Thanks for your help
