Any suggestion/workaround on this one? -Smita

Hi, In YARN distributed shell example, I am setting up my request for containers to the RM using the following call (I am asking for 9 containers here) private ContainerRequest setupContainerAskForRM(Resource capability) {} But when actually RMCallbackHandler allocates containers in following call (I am getting 23 containers here) @Override public void onContainersAllocated(List<Container> allocatedContainers) {} I am getting extra containers which expire after 600 seconds. Will these extra launched containers which are not doing anything will have any performance issue in my application? At one point in my application, out of 19K containers 12K containers expired because they were not used. Can anybody suggest any workaround on this or is it a bug? -Smita
