Jobs are stuck in the ExpressLane pool

Question asked by tonyye on May 15, 2014
I just installed M3 and pig on a single node. Every time I submit a pig job it hangs and stays in the ExpressLane pool with no error reported in any of the log files under /opt/mapr/hadoop/hadoop-0.20.2/log. I also tried killing the jobs via hadoop job <job-id> but none of the jobs are killed even though the command tells me the job was killed. I also tried rebooting the server but all the submitted jobs are still in the ExpressLane pool.
