> 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>
