Changes
-------
Addressed Attila's concerns.
Bugs: AMBARI-21809
https://issues.apache.org/jira/browse/AMBARI-21809
Repository: ambari
Description
-------
Pre-configure (certain) services during a stack upgrade to HDP 2.6, when
Kerberos is enabled, to reduce number of core service restarts when services
are added.
Services to pre-configure include:
* Knox
* Beacon
While upgrading the stack (EU or RU), processing the relevant Kerberos
descriptor to find services marked to be _pre-configured_. When a tagged
service is encountered, process it if it is not installed. Apply only
configuration changes for existing configuration types. This will set at least
the core-site changes related to proxyuser and auth-to-local rules properties.
By doing this, if a tagged service is later installed, the settings will
already be in place in the existing service configs and thus the existing
services will not need to be restarted.
Caveats:
* Default values for the uninstalled, tagged, services will be assumed
* The stack advisor will be used to suggest locations of components - used to
build the clusterHostInfo structure that may be used to derive property values.
Note: This processing is to occur when upgrading the stack from HDP 2.5 to HDP
2.6.
