>                 URL: https://issues.apache.org/jira/browse/AMBARI-9255
>             Project: Ambari
>          Issue Type: Improvement
>    Affects Versions: 1.7.0
>            Reporter: Taeyun Kim
>            Priority: Trivial
>
> YARN Configs Save button is not enabled.
> When a config parameter is changed, 'Discard' button is enabled.
> But 'Save' button is not enabled.
> Not sure from when this is happening, but after some unsuccessful struggle to upgrade HDP2.1 + Ambari 1.6 to HDP2.2 + Ambari 1.7, (it has ATS-related issues) this is happening and blocking the configuration, thus the whole upgrade process.
> When other tab is clicked, 'Discard or Save' dialog is displayed as usual, but when Save button is clicked, nothing is saved.
> This symptom pertains even after the whole cluster + ambari server machine reboot.
