[jira] [Created] (YARN-6630) Container worker dir could not recover when NM restart

Yang Wang created YARN-6630:
-------------------------------

             Summary: Container worker dir could not recover when NM restart
                 Key: YARN-6630
                 URL: https://issues.apache.org/jira/browse/YARN-6630
             Project: Hadoop YARN
          Issue Type: Bug
            Reporter: Yang Wang


When ContainerRetryPolicy is NEVER_RETRY, container worker dir will not be saved in NM state store. Then NM restarts, container.workDir is null, and may cause other exceptions.

{code:title=ContainerLaunch.java}
...
  private void recordContainerWorkDir(ContainerId containerId,
      String workDir) throws IOException{
    container.setWorkDir(workDir);
    if (container.isRetryContextSet()) {
      context.getNMStateStore().storeContainerWorkDir(containerId, workDir);
    }
  }
{code}

{code:title=ContainerImpl.java}
  static class ResourceLocalizedWhileRunningTransition
      extends ContainerTransition {
...
          String linkFile = new Path(container.workDir, link).toString();
...
{code}
