[BUG] Ambari-server login loop

Mon, 11 Sep 2017 16:23:14 -0700 

Hi list,
I have a strange issue suddenly... Ambari lets me log in, but immediately logs me out again with the following messages in /var/log/ambari-server/ambari-server.log: 


11 Sep 2017 23:09:34,790  INFO [ambari-client-thread-78]

These correspond to 1 login/logout loop. As long as I have my browser 
open, this will continue. If I close my browser, the messages stop. Of 
course, this means that I can't use Ambari at all anymore.



Ambari Metrics is set in Maintenance Mode because it can't connect (See 
other mail to mailing list). This started happening when I changed 
"delete.topic.enable" from false to true in Kafka via Ambari.



Restarting Ambari server does not help. Checking the database doesn't 
work either. Clearing browser cache doesn't help...



Any idea what might be going on here? This is with the latest Metron 
code (master, so 0.4.1-rc4 I guess?).
