Hi, I am trying to install cluster via Ambari Web UI "Cluster Install Wizard". At step 7 "Customize Services", got error in browser development Tool console says:
Unable to get property 'hosts' of undefined or null reference. File: app.js, Line: 61178, Column: 9 And the "Cluster install Wizard" Web UI shows error message: Attention: Some configurations need your attention before you can proceed. But no specific configuration is displayed, and I cannot move on since "Next" button is disabled. Could anyone please tell me where I should define this 'hosts' property to fix this problem? Thanks, -Tao
