Hi Dongying, while implementing Oozie On YARN, we tried to avoid the most backward incompatibility issues possible. However, there are some of these still remaining as part as *OOZIE-2889 <https://issues.apache.org/jira/browse/OOZIE-2889>*. It is mostly targeted for Oozie 5.0.0.
Can you please file a JIRA under this umbrella issue w/ the exact steps to reproduce?
