             Summary: Create a callback action 
                 Key: OOZIE-2259
                 URL: https://issues.apache.org/jira/browse/OOZIE-2259
             Project: Oozie
          Issue Type: New Feature
          Components: action
            Reporter: Jaydeep Vishwakarma
            Assignee: Jaydeep Vishwakarma


Need an action to send notification to external server by oozie. We should be 
able to do multiple types of callback, Currently I know jms and http call. It 
should suppose to have capability to call diffrent types of methods along with 
n number of arguments. 
The sample workflow with callback action 
{code:xml}
<workflow-app name="[WF-DEF-NAME]" xmlns="uri:oozie:workflow:0.3">
...
<action name="[NODE-NAME]">
<callback>
        <host>[HOST]</host>
        <method>[METHOD]</command>
        <arg>
                <key>[KEY]</key><value>[VALUE]</value>
        <arg>
            ...
</action>
...
</callback>
...
</workflow-app>
{code}

HOST : by the host system can figure out if it is http or jms callback action. 
System will send the notification to that host.
METHOD : it can be POST/GET/QUEUE/TOPIC
