JonConf in the Hadoop MapReduce is the primary interface used by the user to describe a map-reduce job to the Hadoop framework for execution. The job parameters set in the JobConf cannot be altered if they are marked final by the administrators. Also, some parameters in the JobConf are easy to set while some parameters are relatively more complex for the user to control finely. You can also define other advanced facets of the job such as comparators to be used, files to be put in the DistributedCache, etc in the JobConf.
