--------------------------------------------
Summary: Stack advisor error: argument of type 'NoneType' is not
iterable
Key: AMBARI-13195
URL: https://issues.apache.org/jira/browse/AMBARI-13195
Project: Ambari
Issue Type: Bug
Components: ambari-web
Reporter: Aleksandr Kovalenko
Priority: Blocker
Fix For: 2.1.2
Upgraded from 2.0.2 -> 2.1.2 and tried to perform RU. YARN pre-check requires
to set yarn.timeline-service.recovery.enabled to true. When I try to do that, I
get stack advisor error
