I am using Hadoop 2.6.0 and Oozie 4.1.0. I have to use ChainMapper and ChainReducer in my MapReduce jobs.
While running the Mapreduce job, I am creating .jar using only my Mapper and Reducer Class as Oozie takes care of the Driver functionality. I was trying to look for an example to setup ChainMapper and ChainReducer in Oozie workflow but could not find it. Could you please point me to a documentation/post that could help me how to achieve this.

The ChainMapper and ChainReducer are an extension of the normal Mapper and Reducer. Oozie should only be referencing the one job in which you reference the Chain* and the rest you do within the code.
