      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)
