--------------------------------

project.

> 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>
