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

             Summary: Unable to run OOZIE (MapReduce)  workflow through Falcon Process
                 Key: FALCON-1618
                 URL: https://issues.apache.org/jira/browse/FALCON-1618
             Project: Falcon
          Issue Type: Bug
          Components: oozie
    Affects Versions: 0.6.1, trunk
         Environment: HDP 2.3.2
            Reporter: Saktheesh Balaraj


Error:
Caused by: org.apache.falcon.FalconException: E1004 : E1004: Expression language evaluation
error, Unable to evaluate :${dataIn('input', 'null')}:
        at org.apache.falcon.workflow.engine.OozieWorkflowEngine.dryRunInternal(OozieWorkflowEngine.java:234)

Environment:  HDP2.3.2 Sandbox
Observation:
This could be due to wrong property values in OOZIE coordinator file being generated by Falcon
for an OOZIE workflow (MR).
Current Values:
                <property>
                    <name>falconInPaths</name>
                    <value>${dataIn('input', 'null')}</value>
                </property>

                <property>
                    <name>input</name>
                    <value>${dataIn('input', 'null')}</value>
                </property>
Expected Values:
<property>
                    <name>falconInPaths</name>
                    <value>coord:{dataIn('input', 'null')}</value>
                </property>

                <property>
                    <name>input</name>
                    <value>coord:{dataIn('input', 'null')}</value>
                </property>

Steps to simulate the problem:
1.Install  HDP 2.3.2 Sandbox
	2. Enable Falcon through Ambari
	3. Configure Feed (input), Feed (output)
	4. Configure process with the following configurations
		-input (input Feed)
		-output (output Feed)
	5. Schedule the process through Falcon
