Samarth Gupta commented on FALCON-20:
-------------------------------------

above patch is giving error in feed replication feature. With hadoop 0.20.2 and distcp 1.2.0
following error is coming in the oozie and finally in the tasktracker logs :

The replication action of the instance is failing in oozie. 

attaching cluster and feed xml for which the test was run : cluster01.xml , cluster02.xml
and feed.xml

> Falcon depends on custom DistCp 0.3 since DistCp v2 was part of Hadoop 2.x line. 
> https://issues.apache.org/jira/browse/MAPREDUCE-5081 has back ported DistCp v2 to Hadoop
1.x line and Falcon should instead depend on that.
