Can you try using the YARN Fair Scheduler and set yarn.scheduler.fair.continuous-scheduling-enabled to true?

I'm using Cloudera 5.2.0 and my configuration says
  yarn.resourcemanager.scheduler.class =
org.apache.hadoop.yarn.server.resourcemanager.scheduler.fair.FairScheduler
yarn.scheduler.fair.continuous-scheduling-enabled = true
by default. Changing to a different Scheduler doesn't really change anything, from ACCEPTED to RUNNING always takes about 10 seconds.

Thanks
