Atlas UI not coming up after HDP 3.0.1.0-187, Ambari 2.7.0 upgrade

[#1]

Hi,

I recently upgraded from HDP 2.6.3 to HDP 3.0.1.0-187 & Ambari from 2.6 to 2.7. After the upgrade Atlas UI is not coming up though the service is up and running fine, listening on https port 21443. There is no errors or warnings thrown in the application.log file. The below exception is from the .err log file. Anyone facing the same kind of issues in Altas after the upgrade? Any help would be appreciable.

Atlas version is 1.0.0

Hi @Cibi Chakaravarthi,

Go to Ambari UI>Atlas >Configs (Filter for property atlas.ssl.exclude.cipher.suites)

Set as below and restart the service

atlas.ssl.exclude.cipher.suites=.*NULL.*, .*RC4.*, .*MD5.*, .*DES.*, .*DSS.*

I guess a '.' is missing before *NULL* is your problem.

Please login and accept the answer if this helps you

@Akhil S Naik Thanks for the quick reply. The missing '.' was the issue and the web ui is up now.
