[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>
