Subject [jira] [Commented] (AMBARI-11964) Allow services to hide "custom" configurations
Date Fri, 13 Nov 2015 20:25:10 GMT

    [ https://issues.apache.org/jira/browse/AMBARI-11964?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15004659#comment-15004659

Di Li commented on AMBARI-11964:
--------------------------------

Ambari backend already has such attribute defined for each configType (JIRA AMBARI-7404).
It's called "supports_adding_forbidden". The same as "supports_final", you need to set it
at the configType level. For example, if you want Ambari web UI to not show Custom hdfs-site
for HDFS, you should have the "configuration" section set like this <configuration supports_final="true"
supports_adding_forbidden="true">, in the hdfs-site.xml.

The issue here is that even though the Ambari server backend sends this information to the
UI as a JSON string, UI currently does not process it, thus no show/hide Custom *** sections
behavior observed even when the attribute is set to true.

The patch here proposed a fix to have the UI process the value and show/hide Custom *** sections
accordingly.

> Currently, the logic to hide custom configuration sections in the web UI is hardcoded
in the /ambari-web/app/models/stack_service.js
> {noformat}
> // Add custom section for every configType to all the services
> configTypes.forEach(function (type) {
> var configTypesWithNoCustomSection = ['capacity-scheduler','mapred-queue-acls','flume-conf',
'pig-properties','topology','users-ldif'];
> if (type.endsWith('-env') || type.endsWith('-log4j') || configTypesWithNoCustomSection.contains(type))
{
> return;
> }
> {noformat}
> It will be beneficial to have a declarative way for the Ambari services to hide the custom
configuration section in the web UI for the given configuration XML.
