Mawathage Sanjaya Priyadarshana Medonsa commented on AIRAVATA-959:
------------------------------------------------------------------

org.apache.airavata.xbaya.provenance.ProvenanceReader class provides the output 
data of the previous execution of an experiment on specified node. If Airavata 
is configured to act on provenance and output data is available from a previous 
execution application, then WorkflowInterpreter will set output based on the 
output from previous execution without executing the actual workflow. 

> Provenance Aware workflow processing is not working

> Provenance Aware workflow processing is not working on latest Airavata as 
> expected. Though some of the methods and classes that are part of the 
> Provenance aware workflow processing is available in the source code, it is 
> not part of the main execution flow. Since Provenance Aware workflow 
> processing is an important feature, this issue has been created to track the 
> work needs to be carried out to reintroduce the feature.
