Am I good to go to enable Namenode HA? > Ambari Web UI should validate cluster name. > ------------------------------------------- > > Key: AMBARI-6453 > URL: https://issues.apache.org/jira/browse/AMBARI-6453 > Project: Ambari > Issue Type: Bug > Components: client > Affects Versions: 1.6.1 > Reporter: Pradeep Bhadani > > Ambari Web UI should validate the Hadoop cluster name. > Best practices for choosing the cluster name is to avoid special character and white-spaces . These validation should be there at Ambari Web UI level. > At present Ambari UI "text-box" for cluster name can accept special character like Underscore ( _ ). > If you create Cluster Name having underscore( _ ) , you cannot enable HA. > Reference : http://docs.hortonworks.com/HDPDocuments/HDP2/HDP-2.1.2/bk_system-admin-guide/content/ch_hadoop-ha-3.html > Also , we cannot change the cluster name of existing hadoop cluster. > Reference : https://issues.apache.org/jira/browse/AMBARI-4671 > Above ticket is OPEN. -- This message was sent by Atlassian JIRA (v6.2#6252)
