> # User has ability to rename cluster on 'Cluster Information' page of Ambari
> Admin. Cluster name input isn't being validated there. E.g., it's possible to
> set the new name containing special characters like slash which would break
> API.
> # It's possible to proceed by clicking 'Save' button in rename cluster
> scenario even if it's disabled.
> # Cluster name validation is inconsistent in different possible scenarios of
> its setting. In scope of this task validation on step0 of Ambari installer
> should be changed.
> Validation rules on Ui should be consistent with BE rules.
