Many times, Yarn users want to know the running parameters of a mapreduce job that they have run, and the Conf XML file contents of the job can be viewed from the Web console of the MapReduce history server. Of course, users can also log in to Yarn's Web console address, and then jump from above to the Job history Server Web console for review. This article will demonstrate this feature in a simple graphic example.Steps:1, before starting the Job hist
