Subject [jira] [Created] (AMBARI-22136) Enable server_action tasks defined in EU/RU upgrade pack xml files to take parameters
Date Wed, 04 Oct 2017 19:12:00 GMT
Di Li created AMBARI-22136:
------------------------------

             Summary: Enable server_action tasks defined in EU/RU upgrade pack xml files to
take parameters
                 Key: AMBARI-22136
                 URL: https://issues.apache.org/jira/browse/AMBARI-22136
             Project: Ambari
          Issue Type: Bug
          Components: ambari-server
    Affects Versions: trunk
            Reporter: Di Li
            Assignee: Di Li
             Fix For: trunk


xsi:type="server_action"  tasks defined in EU/RU upgrade pack xml files currently can only
take impClass name, message, scope and summary as parameters.  Since no custom parameters
can pass in, each server_action is basically a special case where all stack/service information
must be hardcoded in the Java logic.

This JIRA proposes a way to pass in custom parameters as shown below (multiple "parameter"
elements). This will allow developers to create general cased server_action that behaves accordingly
to parameters passed in.

<task xsi:type="server_action" class="org.apache.ambari.server.serveraction.upgrades.VerifyExtensionLinkAction">
          <parameter name='a'>a</parameter>
          <parameter name='b'>b</parameter>
          <parameter name='target_stack'>MyStack</parameter>
          <parameter name='target_stack_version'>1.2</parameter>
        </task>
