      Description

      I use Hadoop-Yarn to deploy my real-time distributed computation system, and I get reply from mapreduce-user@hadoop.apache.org to follow these guilders below:

      http://hadoop.apache.org/common/docs/r0.23.0/hadoop-yarn/hadoop-yarn-site/YARN.html
      http://hadoop.apache.org/common/docs/r0.23.0/hadoop-yarn/hadoop-yarn-site/WritingYarnApplications.html
      When I follow the steps to construct my Client, ApplicationMaster. And an issue occurs to me that NM fail to launch a Container because of java.io.FileNotFoundException.

      So the part of NM log has been attached below:

      In order to figure out the fact, I trace back to source code. I find that org.apache.hadoop.yarn.server.nodemanager.DefaultContainerExecutor:

      @Override
      public int launchContainer(Container container,
      Path nmPrivateContainerScriptPath, Path nmPrivateTokensPath,
      String userName, String appId, Path containerWorkDir)
      throws IOException {
      ....
      String[] sLocalDirs = getConf().getStrings(
      YarnConfiguration.NM_LOCAL_DIRS,
      YarnConfiguration.DEFAULT_NM_
      LOCAL_DIRS);
      for (String sLocalDir : sLocalDirs)

      { Path usersdir = new Path(sLocalDir, ContainerLocalizer.USERCACHE); Path userdir = new Path(usersdir, userName); Path appCacheDir = new Path(userdir, ContainerLocalizer.APPCACHE); Path appDir = new Path(appCacheDir, appIdStr); Path containerDir = new Path(appDir, containerIdStr); lfs.mkdir(containerDir, null, false); }

      ....

      lfs.mkdir(containerDir, null, false); refer to the api of mkdir, false means cannot create parent path here if not exists.
      In my hadoop project, I revise lfs.mkdir(containerDir, null, false); to lfs.mkdir(containerDir, null, true); , then my program goes well.
