Description

1. On the Ambari dashboard, navigate to Alerts. Click on an alert.
2. Click on the Edit button and note that there is no validation and you can enter characters such as \, < etc.
3. Also note that you can enter more than 255 characters. However, if the number of characters exceeds 255, an exception is thrown on the server side because the database column only allows 255 characters. The UI however does not restrict this and you get no error message. The value in the UI gets reset to what it was before you added more than 255 characters since the update failed.
