-------------------------------------
Summary: Moving Hive Metastore gets hanged in Ambari due to
Uncaught TypeError: Cannot read property 'tag' of undefined
Key: AMBARI-23413
URL: https://issues.apache.org/jira/browse/AMBARI-23413
Project: Ambari
Issue Type: Bug
Components: ambari-web
Affects Versions: trunk, 2.7.0
Reporter: JaySenSharma
Assignee: 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.
