title: Is there a way to kill reducer task in Hadoop?
body: <p>Running a few map reduce jobs and one job takes over the all the reducer capacity. Is there a way to kill one or two reducer tasks to free up the cluster?</p>
  
  <p>I can go directly to the one of the task tracker server and kill the java process manually. But I am wondering if there is a more decent way to do this?</p>
