      Description

      MAPREDUCE-2051 added a system test for the fair scheduler which starts a minicluster and runs a couple jobs with preemption on. I recently found a deadlock in a previous version of the scheduler that was due to lock inversion between the scheduler servlet and some JT internals. I'd like to modify the existing system test to also hit the /scheduler servlet, allowing jcarder to detect such lock inversions in the future.
