----------------------------------------
Summary: Add Upgrade Logic For Removal of clusterconfigmapping
Key: AMBARI-20055
URL: https://issues.apache.org/jira/browse/AMBARI-20055
Project: Ambari
Issue Type: Task
Components: ambari-server
Affects Versions: trunk
Reporter: Jonathan Hurley
Assignee: Jonathan Hurley
Priority: Critical
Fix For: trunk
The Ambari upgrade scripts should now perform the following operations:
- Adding the following columns / constraints to the {{clusterconfig}} table:
-- {{selected SMALLINT NOT NULL DEFAULT 0}} - whether or not the configuration
is currently selected
-- {{selected_timestamp BIGINT NOT NULL DEFAULT 0}} - the last time that the
configuration was marked as {{selected}}
-- A constraint preventing the same type to have more than 1 selected rows
- Finding all {{selected}} mappings in {{clusterconfigmapping}} and marked
their associated entry in {{clusterconfig}} as {{selected}}
- Removal of the {{clusterconfigmapping}} table.
