Empty Page - Falcon Web UI

arunak — Tue, 30 Aug 2016 12:25:31 GMT

Hi All, I just added the falcon service to my cluster using the ambari "add service". Logged into the host running the falcon server and verified the falcon service. The service is running as expected. However, when I launch the falcon webpage, it asks me a user name. I keyed in the default ambari-qa and there after it never prompted me a password. It just displays a webpage with three links that route back to the same page. The links are Data Set, Processes, Clusters Could you point out what could be the issue? Below are the log line that I could gather from the server

@Arun A K

Which version of Falcon you are using. The links which you are seeing will show details about the submitted feed (data) entity, submitted/schedueld process entity and cluster entity.

@peeyush I am running HDP-2.2.9.0-3393 with Falcon 0.6.0.2.2. The problem here is that though I have the urls, clicking on them does not yield any action. I don't get any error messages too.

@Arun A K Thanks for specifying the version. Have you done a successful submission of Falcon entities like (Cluster,Feed and process) from CLI before clicking these URL's from Falcon UI.

Hi @peeyush, no I have not used the cli. I was expecting I could create a cluster using the web page. This is my Hello World on falcon. So was following http://hortonworks.com/hadoop-tutorial/create-falcon-cluster/. Does this not apply to my version of HDP and Falcon?

@Arun A K

Yes, above article does not apply to your version. You are using older version.

@Arun A K

Please do some Entity submission from Falcon CLI and then you can see submitted and scheduled entities on Falcon UI. The version you are using in that view capability of submitted entities is only available.
