Saktheesh Balaraj updated FALCON-1618:
--------------------------------------
    Description: 
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
