      Description

      While running GridMixV3, one of the jobs got stuck for 15 hrs. After clicking on the Job-page, found one of its reduces to be stuck. Looking at syslog of the stuck reducer, found this:

      Which means that tasks is supposed to have stopped within 20 secs, whereas the process itself is stuck for more than 15 hours. From AM log, also found that this task was sending its update regularly. ps -ef | grep java was also showing that process is still alive.
