---------------------------------------
Summary: Blueprints: fix stale configs and kerberos-env stack
defaults are not being applied during cluster deployment
Key: AMBARI-14251
URL: https://issues.apache.org/jira/browse/AMBARI-14251
Project: Ambari
Issue Type: Bug
Components: ambari-server
Affects Versions: 2.2.0
Reporter: Sandor Magyari
Assignee: Sandor Magyari
Fix For: 2.2.0
The following issues were discovered during Kerberized cluster deployment using
Blueprints:
1. Stale configuration problem: Kerberos related configuration is generated for
each host separately but applied on the whole Cluster. In case two components
having common config types (like core-site in case of YARN_CLIENT and
RESOURCEMANAGER) are deployed on two different hosts, Kerberos configuration
changes generated by one host may interfere with config types deployed on other
host. Eg. host2 modifies properties in core-site for RESOURCEMANAGER when same
config type is already pushed to host1, causing Ambari to consider host1 with
steal config.
2. Stack default values for properties in kerberos-env and krb5-conf are not
being applied during cluster deployment in case they are defined only in
Cluster create template configurations
