             Summary: Nodemanager container after ext3 folder limit
                 Key: YARN-6708
                 URL: https://issues.apache.org/jira/browse/YARN-6708
             Project: Hadoop YARN
          Issue Type: Bug
            Reporter: Bibin A Chundatt
            Priority: Critical


Configure umask as *027* for nodemanager service user
and {{yarn.nodemanager.local-cache.max-files-per-directory}} as {{40}}. After 4  *private* dir localization next directory will be *0/14*


Local Directory cache manager

drwxr-s--- 4 mapred hadoop 4096 Jun 10 12:07 ../
drwxr-x--- 3 mapred users  4096 Jun 10 14:36 0/

drwxr-xr-x 3 mapred users  4096 Jun 10 12:31 13/

{code}

*drwxr-x---* 3 mapred users  4096 Jun 10 14:36 0/ is only *750*
Nodemanager user will not be able check for localization path exists or not.

{{LocalResourcesTrackerImpl}}
{code}
    case REQUEST:
      if (rsrc != null && (!isResourcePresent(rsrc))) {
        LOG.info("Resource " + rsrc.getLocalPath()
            + " is missing, localizing it again");
        removeResource(req);
        rsrc = null;
      }
      if (null == rsrc) {
        rsrc = new LocalizedResource(req, dispatcher);
        localrsrc.put(req, rsrc);
      }
      break;
{code}

*isResourcePresent* will always return false and same resource will be localized to {{0}} to next unique number
