Sowmya Ramesh created FALCON-1420:
-------------------------------------
Summary: NPE in MetadataMappingService when adding process
instance executed
Key: FALCON-1420
URL: https://issues.apache.org/jira/browse/FALCON-1420
Project: Falcon
Issue Type: Bug
Affects Versions: 0.7
Reporter: Sowmya Ramesh
FALCON-1091 changed value of property
WorkflowExecutionArgs.OUTPUT_FEED_NAMES.getName() "NONE" to "IGNORE" in
ProcessExecutionCoordinatorBuilder.initializeOutputPaths which has introduced
the bug. For a process if there are no output feed MetadataMappingService
should not go ahead to add output feed instance.
