Hi, I am running the distributed shell example of YARN on apache Hadoop 2.4.0. I have implemented getProgress method in my ApplicationMaster as follows public float getProgress() { // set progress to deliver to RM on next heartbeat float progress = 0; try{ progress = (float) numCompletedContainers.get() / numTotalContainers.get(); } catch(Exception _ex) { _ex.printStackTrace(); } return progress; } While shutting down the application I get following excpetion - Interrupted while waiting for queue java.lang.InterruptedException at java.util.concurrent.locks.AbstractQueuedSynchronizer$ConditionObject.reportInterruptAfterWait(AbstractQueuedSynchronizer.java:2017) at java.util.concurrent.locks.AbstractQueuedSynchronizer$ConditionObject.await(AbstractQueuedSynchronizer.java:2052) at java.util.concurrent.LinkedBlockingQueue.take(LinkedBlockingQueue.java:442) at org.apache.hadoop.yarn.client.api.async.impl.AMRMClientAsyncImpl$CallbackHandlerThread.run(AMRMClientAsyncImpl.java:275) When I restart my application I get following error java.lang.IllegalArgumentException: Progress indicator should not be negative Because of this, my ApplicationMaster is launched in another container. This exception is coming all the time in above scenario. Can you suggest me what is going wrong? Thanks, Smita
