-------------------------------------------
Summary: Rolling Upgrade - Bootstrap cluster to support RUs
Key: AMBARI-8147
URL: https://issues.apache.org/jira/browse/AMBARI-8147
Project: Ambari
Issue Type: Story
Components: ambari-server
Affects Versions: 2.0.0
Reporter: Alejandro Fernandez
Assignee: Alejandro Fernandez
Fix For: 2.0.0
1. Create new tables and populate during the installation of a new cluster.
*clusterversion* table
||Column||Type||Keys||Example||
|id|BIGINT|PK|1|
|cluster_id|BIGINT|FK|2|
|stack|VARCHAR(255)| |HDP-2.2 |
|version|VARCHAR(255)| |HDP-2-2.0.1-885 |
|state| VARCHAR(32) | |INSTALLED, CURRENT, UPGRADING, UPGRADE_FAILED |
|start_time|DATETIME| |2014-10-31 14:00:00|
|end_time|DATETIME| |2014-10-31 15:00:00|
|user_name|VARCHAR(32)| |admin|
*hostcomponentstate* table
Add column upgrade_state VARCHAR(32) ("NONE" is the default, "UPGRADING",
"UPGRADE_FAILED")
*hostversion* table
||Column||Type||Keys||Example||
|id|BIGINT|PK|1|
|host_name|VARCHAR(255)|FK hosts.name|c6401.ambari.apache.org|
|stack|VARCHAR(255)| |HDP-2.2|
|version|VARCHAR(255)| |2.2.0.1-885|
|state|VARCHAR(32)| |INSTALLED, CURRENT, NOT_INSTALLED|
2. Whenever adding a host or service, update the tables above.
Adding a host already populates the *hostcomponentstate* table, so the
upgrade_state column needs to have a default value.
Adding a host needs to look up the currently installed stack, and add a record
for the host in the *hostversion* table.
3. The upgrade from Ambari 1.7.0 to Ambari 2.0.0 should create these tables,
and bootstrap them with data.
