Oleg Nechiporenko commented on AMBARI-2508:
-------------------------------------------
Yusaku Sako, if we modify field content (replace spaces with "new-line"
character), we'll get situation when user just load page and get "Undo" link
near the "hadoop.security.auth_to_local" field.
> Preserve (or make sure to add) newlines in core-site.xml's
> hadoop.security.auth_to_local

> We made some changes so that if a property value contains a newline, it is
> displayed as a textarea.
> When added via the security wizard, core-site.xml's
> hadoop.security.auth_to_local does not contain any newlines. The rules
> should be separated by newlines so that the value is shown as a textarea.
> Otherwise it's extremely difficult to review and edit.
