> Steps:
> 1. Go to "Services" page.
> 2. Select "HDFS" service.
> 3. Select "Configs" tab.
> 4. Open "Custom core-site.xml" panel.
> 5. Add property with name "ipc.client.idlethreshold" to this panel.
> Result:
> Property with name "ipc.client.idlethreshold" was added to "Custom
> core-site.xml" panel. But there is already presented property with same name
> in "core-site.xml" file. After saving added property was disappeared from UI,
> and after service starting value of the old was changed to new (on UI and in
> "core-site.xml" file).
> Expected result:
> UI should not allow to add property with existing name in specified file.
