> Feed Replication workflows are failing

>                 Key: FALCON-437
>                 URL: https://issues.apache.org/jira/browse/FALCON-437
>             Project: Falcon
>          Issue Type: Bug
>    Affects Versions: 0.5, 0.6
>            Reporter: Satish Mittal
>            Priority: Blocker
>
> With latest trunk, feed replication workflows are failing with ClassNotFoundException
for falcon lib classes (LateDataHandler and FalconPostProcessing).
> Noticed that in mapred.job.classpath.files conf property of replication jobs, none of
falcon workflow lib jars are getting added. Hence the exception.
> Also noticed that when feed is scheduled, the lib folder is not getting created on HDFS
at default appPath location. 
> e.g. when replication appPath is:
> {noformat}
> ${nameNode}/projects/falcon/hcolo2/staging/falcon/workflows/feed/hcat-in-repl3/1399545050032/REPLICATION/hcat-cluster1
> {noformat}
> the lib folder is getting created at:
> {noformat}
> /projects/falcon/hcolo2/staging/falcon/workflows/feed/hcat-in-repl3/1399545050032/REPLICATION
> {noformat}
> It looks to be a regression due to FALCON-390.
