> Key: YARN-2354
> URL: https://issues.apache.org/jira/browse/YARN-2354
> Project: Hadoop YARN
> Issue Type: Sub-task

>
> To reproduce, run distributed shell with -num_containers option,
> In ApplicationMaster.java, the following code has some issue.
> {code}
> int numTotalContainersToRequest =
> numTotalContainers - previousAMRunningContainers.size();
> for (int i = 0; i < numTotalContainersToRequest; ++i) {
> ContainerRequest containerAsk = setupContainerAskForRM();
> amRMClient.addContainerRequest(containerAsk);
> }
> numRequestedContainers.set(numTotalContainersToRequest);
> {code}
> numRequestedContainers doesn't account for previous AM's requested
> containers. so numRequestedContainers should be set to numTotalContainers
