-------------------------------------
Summary: Enhanced the ability to compute whether an execute-stage
should be included in the stack upgrade/downgrade work flow
Key: AMBARI-18352
URL: https://issues.apache.org/jira/browse/AMBARI-18352
Project: Ambari
Issue Type: Task
Components: ambari-server
Affects Versions: 2.4.1
Reporter: Robert Levas
Assignee: Nate Cole
Fix For: 2.5.0
Add a way to compute whether an execute-stage should be included, other than
the simple service/component check.
For example some stage should only be executed if the cluster has Kerberos
enabled. This can be determined using the {{cluster-env/security_enabled}}
flag; or (better yet) the {{Cluster}}'s {{securityType}} property, which would
be set to "KERBEROS".
Currently the only filter is based on service and component, which does not
work in the case of Kerberos since Kerberos can be enabled without needing to
install the KERBEROS service or the KERBEROS_CLIENT component. This will happen
if the Kerberos identities are managed manually rather than configuring Ambari
to do it by integrating with a supported KDC.
