I want to create a variable that should be available to all the actions in the Oozie workflow. I have tried to create it as shown below. But EL expression is not getting evaluated resulting in variable current_ts value as EL expression itself. Can somebody please throw some light on this? <workflow-app xmlns="uri:oozie:workflow:0.4" name="no-op-wf">
<parameters>
<property>
<name>current_ts</name>
<value>${replaceAll((replaceAll((replaceAll((timestamp()),"-","")),"T","_")),":","")}</value>
</property>
</parameters>
<start to="test"/>
<kill name="test">
<!--message Just to show that this expression works if used here>Timestamp - [${replaceAll((replaceAll((replaceAll((timestamp()),"-","")),"T","_")),":","")}</message-->
<message>Timestamp - ${current_ts}</message> <!-- this will print expression but not evaluate it -->
</kill>
<end name="end"/>
</workflow-app>
