---------------------------------------

             Summary: RM cycles through container ids for an app that is waiting for resources.

                 Key: YARN-5074
                 URL: https://issues.apache.org/jira/browse/YARN-5074
             Project: Hadoop YARN
          Issue Type: Bug
          Components: resourcemanager
    Affects Versions: 2.7.2
            Reporter: Sidharta Seethana


/cc [~wangda], [~vinodkv]

This was observed on a cluster running a 2.7.x build. Here is the scenario :

1. A YARN cluster has applications running that almost entirely consume the cluster, with
little available resources.
2. A new app is submitted - the resources required for the AM exceed what is available in
the cluster. The app stays in the 'ACCEPTED' state till resources are available.
3. Once resources are available and the AM container comes up, the AM container has a id that
indicates that the RM has been cycling through containers. There are no errors in the logs
of any kind. One example id for such an AM container is : container_e3788_1462916288781_0012_01_000302
. This indicates that while the app was in the 'ACCEPTED' state, the RM cycled through 301
containers.
