Make cluster name inputs validation in Ambari UI consistent

    XMLWordPrintableJSON

Details

    Description

      1. 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.
      2. It's possible to proceed by clicking 'Save' button in rename cluster scenario even if it's disabled.
      3. 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.
