[jira] [Updated] (AMBARI-22337) each service should be able to
implement server actions, package them add a jar to be loaded during EU
[ https://issues.apache.org/jira/browse/AMBARI-22337?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Di Li updated AMBARI-22337:
---------------------------
Description:
xsi:type="server_action" tasks defined in EU/RU upgrade pack xml files currently can only classes from Ambari source code. This limites the server action that custom services / services from mpacks can perform. This JIRA proposes a way to allow each service to implement server action classes, package them in a jar to be loaded during EU
1. Each service can have a server_actions (support stack inheritance) such as /var/lib/ambari-server/resources/stacks/HDP/2.5/services/ZOOKEEPER/server_actions.
a) The dir contains jar for the server action classes.
_/var/lib/ambari-server/resources/stacks/HDP/2.5/services/ZOOKEEPER/server_actions
[root@~ server_actions]# ll
total 8
-rw-r--r-- 1 root root 7510 Oct 30 10:49 test_full.jar_
2. upgrade pack can then invoke the server action as shown below
<!-- server action test without specifying a service in the execution stage-->
<group xsi:type="cluster" name="TEST_A" title="Test abc">
<execute-stage title="aaaa">
<task xsi:type="server_action" class="org.apache.ambari.server.serveraction.upgrades.SATestWithoutService"/>
</execute-stage>
</group>
<!-- server action test with a service specified in the execution stage-->
<execute-stage service="ZOOKEEPER" component="ZOOKEEPER_SERVER" title="Parame
terizing Zookeeper Log4J Properties">
<task xsi:type="server_action" class="org.apache.ambari.server.serveraction.upgrades.SATestWithService">
<summary>zkpr test</summary>
</task>
</execute-stage>
