Metron 0.4 Alert UI is Empty

[#1]

I have installed Metron 0.4.x in Ubuntu 14.

I have started REST, Metron Management and Alert UI. But Alert is always empty for any search criteria.

Is there any guideline to use alert UI.

Note: Data available in Elasticsearch

Thanks @asubramanian,

I have cleared the existing Elasticsearch indices. We have installed the Metron 0.4.1 manually in Ubuntu 14 as per the steps provided below URL, https://community.hortonworks.com/articles/88843/manually-installing-apache-metron-on-ubuntu-1404.ht... Uploaded Elasticsearch templates into ES and executed sensor-stubs. Now it is working.
