Jian He created YARN-2354:
-----------------------------

             Summary: DistributedShell may allocate more containers than client specified after it restarts
                 Key: YARN-2354
                 URL: https://issues.apache.org/jira/browse/YARN-2354
             Project: Hadoop YARN
          Issue Type: Sub-task
            Reporter: Jian He


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
