Adding propagate-configuration tag in parent workflow xml file resolved the issue.

<workflow-app xmlns = "uri:oozie:workflow:0.4" name = "Parent-Workflow">
<start to = "workflowAction1" />
<action name = "workflowAction1">
<sub-workflow>
<app-path>/user/user1/oozie-workflow/subWorkflow1.xml</app-path>
<propagate-configuration />
</sub-workflow>
<ok to = "end" />
<error to = "end" />
