-------------------------------------------------------------------
[~saktheesh] Is it possible for you to share the Falcon cluster, feed and
process entity to debug this issue. It is quite strange that you are getting
this issue as on HDP cluster, I have several times executed the Oozie MR
workflow through Falcon without any issues.
