> Project: Ambari
> Issue Type: Bug
> Components: ambari-server, ambari-web
> Affects Versions: trunk, 2.7.0
> Reporter: JaySenSharma

> In Ambari 2.7, when we try to move the Hive Metastore to a new host then at
> Wizard Step-3 it hangs. When we look at the ambari UI Browser Developer
> Console then we notice the following error:
> {code}
> app.js:31183 Uncaught TypeError: Cannot read property 'tag' of undefined
> at app.js:31183
> at Array.forEach (<anonymous>)
> at Class.getConfigUrlParams (app.js:31182)
> at Class.onLoadConfigsTags (app.js:31167)
> at Class.opt.success (app.js:180694)
> at fire (vendor.js:1141)
> at Object.fireWith [as resolveWith] (vendor.js:1252)
> at done (vendor.js:8178)
> at XMLHttpRequest.callback (vendor.js:8702)
> {code}
> On further debugging it is found that when the site = webhcat-site then it
> shows this error because this site is not present inside the desired_configs.
> Hence there should be a check before attempting to read it's tag information.
> *Steps to Reproduce the issue:*
> - Install Hive Service to the cluster.
> - Now attempt to move the Hive MetaStore to another host using ambari UI.
