------------------------------------
> Storm config page not available
> -------------------------------
>
> Key: AMBARI-5159
> URL: https://issues.apache.org/jira/browse/AMBARI-5159
> Project: Ambari
> Issue Type: Bug
> Components: client
> Affects Versions: 1.5.1
> Reporter: Oleg Nechiporenko
> Assignee: Oleg Nechiporenko
> Fix For: 1.5.1
>
> Attachments: AMBARI-5159.patch, ui.childopts-warning msg.png,
> ui.childopts.png
>
>
> Storm Config page not available.
> There is javascript-error.
> ui.childopts-property doesn't have a default value and Storm config-validator
> fails with checking this property.
> The current behavior is that the {{ui.childopts}} is displayed without any
> defaultValue (screenshot attached). The validator doesn't invalidate this
> property which has no value. Going ahead this property is silently deleted
> while applying configurations and does not appear in the service config page
> post-installation.
> The motive in the commit was to fetch the defaultValue from the stack instead
> of redeclaring it on client side.
> In this ticket we need to address following issues:
> # The default value for properties are being redeclared in {{getDefaults}}
> function of storm_defaults_provider.js. We should fetch the defaultValue from
> the stack and should not hard-code it in the client code. Actually the
> default value for ui.childopts got changed in the stack definition with an
> earlier commit and it was not being reflected on service config page as this
> was not changed in the client code.
> # Blank values should be marked as invalid. As of current behavior
> ui.childopts with no value is not marked invalid. This is actually marked as
> invalid if user populate it once and then clear it.
> # Once we fetch the defaultValue from the stack for {{ui.childopts}} and
> change the property value, the displayed warning message states the entire
> value as {{Value is less than the recommended default of -Xmx768m
> -Djava.security.auth.login.config=/etc/storm/storm_jaas.conf}} (screenshot
> attached). The warning message should only include Xmx part and not other
> java options.
