Unable to open Atlas UI

[#1]

Hi,

I have created HDP 2.6 on AWS. I have registered atlas port 21000 to master node and set atlas.server.bind.address to the host on which atlas service is running But Atlas UI is not working.I have loaded sample data to atlas server successfully still Atlas UI not working.

What the permissions on the atlas file? was it started using ambari or manually?

Check Atlas process

$ ps aux | grep -i Atlas 

Check whether the port is listening

$ netstat -an | grep 21000 | grep -i listen

Do you have any errors in /var/log/Atlas etc

I have set 777 permission on /var/log/atlas.I was starting Atlas service from Ambari UI

Could you please check application logs for any exceptions and if there are any , can you please paste here ? also , please check network tab and console tab for any errors. What is the response of http://atlashost:21000 in console tab ? and what is displayed on UI ? Can you check if the issue is https://issues.apache.org/jira/browse/ATLAS-1199 ?

This log shows up when we stop Atlas. Can you please check the logs when you start Atlas and UI doesn't show up ?
