Hi Anil,I never used Chain(Mapper/Reducer).I think in Oozie you have two
options:1. Run an independent hadoop job. For RM/JHS UI, go to the job
configurations page. Identify what are the properties added for ChainMR. Come
back to Oozie workflow.xml. Add those properties into the MR action
configuration section. This is preferable approach.
2. Write a java action that will submit your job following the ChainMR concept.
However, this has some shortcomings.

Hi,
I am using Yarn 2.4.0 and Oozie 4.0. I have to use ChainReducer in one of
my MapReduce job. I was trying to look for an example to setup ChainReducer
in Oozie workflow but could not find it. Also, the jobconf setup of
ChainReducer is slightly different from a normal Hadoop job. So, i cannot
setup this job just like a simple oozie workflow.
Can anyone point me to a documentation/post that could help me understand
how to achieve this.
My MR job has following flow: Mapper -> Reducer-> Mapper
